Description

TP151x series are CMOS single/dual/quad op-amps with low offset, stable high frequency response, low power, low supply voltage, and rail-to-rail inputs and outputs. They incorporate 3PEAK ’s proprietary and patented design techniques to achieve best in-class performance among a ll micro -power CMOS amplifiers in its power class. The TP151x family can be used as plug -in replacements for many commercially available op -amps to reduce power and improve input/output range and performance. TP151x are unity gain stable with Any Capacitive load with a constant 150kHz GBWP, 0.09V/μs slew rate while consuming only 4μA of quiescent current per amplifier . Analog trim and calibration routine reduce i nput offset voltage to below 3.0mV, and proprietary precision temperature compensation technique makes offset voltage temperature drift at 0.6μV/°C. Beyond the rails input and rail -to-rail output characteristics allow the full power -supply voltage to be used for signal range. This combination of features makes the TP151x OPA ideal choices for battery -powered applications because they minim ize errors due to power supply voltage variations over the lifetime of the battery and maintain hi gh CMRR even for a rail -to-rail input op-amp. Battery Current Monitor, consumer devices, handheld instrumentation, Remote battery-powered sensors, hazard detection (for example, smoke, fire, and gas), and patient monitors can benefit from the features of the TP151x op-amps. For applications that require power -down, the TP1511N in popular type packages has a low-power shutdown mode that reduces supply current to less than 0. 1μA, and forces the output into a high-impedance state. 3PEAK and the 3PEAK logo are registered trademarks of 3PEAK INCORPORATED.

TP1511/TP1511N/TP1512/TP1514 Stable 150kHz, 4μA, Rail-to-Rail, EveryCapTM Op Amps www.3peakic.com.cn REV A Pin Functions –IN: Inverting Input of the Amplifier. Voltage range of this pin can go from V– – 0.3V to V+ + 0.3V. +IN: Non-Inverting Input of Amplifier. This pin has the same voltage range as –IN. +VS: Positive Power Supply. Typically the voltage is from 2.1V to 5.25V. Split supplies are possible as long as the voltage between V+ and V– is between 2.1V and 5.25V. 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. -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 2.1V to 5.25V. If it is not connected to ground, bypass it with a capacitor of 0.1μF as close to the part as possible. SHDN: Active Low Shutdown. Shutdown threshold is 1.0V above negative supply rail. If unconnected, the amplifier is automatically enabled. OUT: Amplifier Output. The voltage range extends to within millivolts of each supply rail. N/C: No Connection. Operation The TP151x family input signal range extends beyond the negative and positive power supp lies. The output can even extend all the way to the negative supply. The input stage is comprised of two CMOS differential amplifiers, a PMOS stage and NMOS stage that are active over different ranges of common mode input voltage. 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 Low Supply Voltage and Low Power Consumption The TP151x family of operational amplifiers can operate with power supply voltages from 2.1V to 6.0 V. Each amplifier draws only 4μA quiescent current. The low supply voltage capability and low supply current are ideal for portable applications demanding HIGH CAPACITIVE LOAD DRIVING CAPABILITY and STABLE WIDE BANDWIDTH. The TP151x family is optimized for wide bandwidth low power applications. They have an industry leading high GBW to power ratio and are unity gain stable for ANY 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 TP151x family provides a low input referred noise of 95nV/√Hz at 1kHz. The noise density will grow slowly with the frequency in wideband range, and the input voltage noise density is typically 3.6μVP-P at the frequency of 0.1Hz to 10Hz. Low Input Offset Voltage and Low Offset Voltage Temperature Drift The TP151x family has a low offset voltage of 3.0mV maximum which is essential for precision applications. The offset voltage is trimmed with a proprietary trim algorithm to ensure low offset voltage for pre cision signal processing requirement . 3PEAK’s p roprietary precision temperature compensation techn ique makes offset voltage temperature drift at 0.6μV/°C.

TP1511/TP1511N/TP1512/TP1514 Stable 150kHz, 4μA, Rail-to-Rail, EveryCapTM Op Amps REV A www.3peakic.com.cn Low Input Bias Current The TP151x family 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 In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be considered. Surface lea kage 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 TP151x 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 voltage as the sensitive pin. An example of this type of layout is shown in Figure 2 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., VDD/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 2 Ground Sensing and Rail to Rail Output The TP151x family has excellent output drive c apability, delivering over 10mA 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 500mV 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 amplifier 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 TP151x family has reverse -biased ESD protection diodes on all inputs and output. Input and out pins can not be biased more than 300mV beyond either supply rail. Shut-down The single channel OPA versions have S HDN pins that can shut down the amplifier to less tha n 0.1μA supply current. The SHDN pin voltage needs to be within 0.5V of V– for the amplifier to shut down. During shutdown, the output will be in high output resistance state, which is suitable for multiplexer applications. When left floating, the SHDN pin is internally pulled up to the positive supply and the amplifier remains enabled.
