Description

LM321/358/324 types consist of single/dual/quad channel independent, high gain, internally frequency compensated operational amplifiers which are designed specifically to operate from a single power supply over a wide range of voltages. They may also be operated from split power supplies. The supply current is basically independent of the supply voltage over the recommended voltage range. These devices are particularly useful in interfac e circuits with digital systems and can be operated from the single common 5V DC power supply. They are also intended for transducer amplifiers, DC gain blocks and many other conventional op amp circuits which can benefit from the single power supply capability. In the linear mode, the input common -mode voltage range includes ground and the output voltage can also swing to both ground and power rail , even though operated from a single power supply. The LM321 is single channel version available in 5-pin SOT23 packages. The LM358 is dual channel version available in 8-pin SOP and MSOP packages. The LM324 is quad channel version available in 14-pin SOP and TSSOP packages. 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals. Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input current should be limited to less than 10mA. Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads.

8 Rev. B.01 www.3peakic.com.cn LM321 / LM358 / LM324 1.2MHz, Low-Power 36V Op Amps Pin Functions -IN: Inverting Input of the Amplifier. +IN: Non-Inverting Input of Amplifier. OUT: Amplifier Output. The voltage range extends to within mV of each supply rail. V+ or +Vs: Positive Power Supply. Typically the voltage is from 3V to 36V. Split supplies are possible as long as the voltage between V+ and V– is between 3V and 36V. A bypass capacitor of 0.1μF as close to the part as possible should be used between power supply pins or between supply pins and ground. V- or -Vs: Negative Power Supply. It is normally tied to ground. It can also be tied to a voltage other than ground as long as the voltage between V+ and V– is from 3V to 36V. If it is not connected to ground, bypass it with a capacitor of 0.1μF as close to the part as possible. Operation The LM321/358/324 output signal range extends beyond the negative and positive power supplies. The intput can even extend all the way to the negative supply. The Class-AB control buffer and output bias stage uses a proprietary compensation technique to take full advantage of the process technology to drive very high capacitive loads. This is evident from the transient over shoot measurement plots in the Typical Performance Characteristics. Applications Information High Supply Voltage and Low Power Consumption The LM321/358/324 of operational amplifiers can operate with power supply voltages from 3V to 36V. Each amplifier draws only 100μA quiescent current. The low supply voltage capability and low supply current are ideal for portable applications demanding HIGH CAPACITIVE LOAD DRIVING CAPABILITY and W IDE BANDWIDTH. The LM321/358/324 is optimized for wide bandwidth low power applications. They have an industry leading high GBWP to power ratio and are unity gain stable for 10nf CAPACITIVE load. When the load capacitance increases, the increased capacitance at the output pushed the non -dominant pole to lower frequency in the open loop frequency response, lowering the phase and gain margin. Higher gain configurations tend to have better capacitive drive capability than lower gain configurations due to lower closed loop bandwidth and hence higher phase margin. Low Input Referred Noise The LM321/358/324 provides a low input referred noise density of 48nV/√Hz at 1kHz. The voltage noise will grow slowly with the frequency in wideband range, and the input voltage noise is typically 10μVP-P at the frequency of 0.1Hz to 10Hz. Low Input Offset Voltage The LM321/358/324 has a low offset voltage tolerance of 3mV maximum which is essential for precision applications. The offset voltage is trimmed with a proprietary trim algorithm to ensure low offset voltage for precision signal processing requirement. Low Input Bias Current The LM321/358/324 is a CMOS OPA family and features very low input bias current in pA range. T he low input bias current allows the amplifiers to be used in applications with high resistance sources. Care must be taken to minimize PCB Surface Leakage. See below section on “PCB Surface Leakage” for more details. PCB Surface Leakage

1.2MHz, Low-Power 36V Op Amps In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 10 12Ω. A 5V difference would cause 5pA of current to flow, which is greater than the LM321/358/324 OPA’s input bias current at +27° C (± 1pA, typical). It is recommended to use multi-layer PCB layout and route the OPA’s -IN and +IN signal under the PCB surface. The effective way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltag e as the sensitive pin. An example of this type of layout is shown in Figure 1 for Inverting Gain application. 1. For Non-Inverting Gain and Unity-Gain Buffer: a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the Common Mode input voltage. 2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors): a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op-amp (e.g., VS/2 or ground). b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface. VIN+ VIN- +VSGuard Ring Figure 1 Ground Sensing and Rail to Rail Output The LM321/358/324 has excellent output drive capability, delivering over 35mA of output drive current. The output stage is a rail -to-rail topology that is capable of swinging to within 5mV of either rail. Since the inputs can go 100mV beyond either rail, the op-amp can easily perform ‘True Ground Sensing’. The maximum output current is a function of total supply voltage. As the supply voltage to the amplifie r increases, the output current capability also increases. Attention must be paid to keep the junction temperature of the IC below 150° C when the output is in continuous short-circuit. The output of the amplifier has reverse-biased ESD diodes connected to each supply. The output should not be forced more than 0.5V beyond either supply, otherwise current will flow through these diodes. ESD The LM321/358/324 has reverse-biased ESD protection diodes on all inputs and output. Input and out pins cannot be biased more than 200mV beyond either supply rail. Feedback Components and Suppression of Ringing Care should be taken to ensure that the pole formed by the feedback resistors and the parasitic capacitance at the inverting input does not degrade stability. For example, in a gain of +2 configuration with gain and feedback resistors of 10k, a poorly designed circuit board layout with parasitic capacitance of 5pF (part +PC board) at the amplifier’s inverting input will cause the amplifier to ring due to a pole formed at 1.2MHz. An additional capacitor of 5pF across the feedback resistor as shown in Figure 2 will eliminate any ringing. Careful layout is extremely important because low power signal conditioning applications demand high -impedance circuits. The layout should also minimize stray capacitance at the OPA’s inputs. However some stray capacitance may be unavoidable and it may be necessary to add a 2pF to 10pF capacitor acros s the feedback resistor. Select the smallest capacitor value that ensures stability.
