APPLICATIONS

Dual/Quad 80MHz, 25V/µs Low Power Rail-to-Rail Input and Output Precision Op Amps The LT®1801/LT1802 are dual/quad, low power, high speed rail-to-rail input and output operational amplifi ers with excellent DC performance. The LT1801/LT1802 feature reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth. Typically, the LT1801/LT1802 have an input offset voltage of less than 100μV, an input bias current of less than 50nA and an open-loop gain of 85 thousand. T h e L T 1 8 0 1 / L T 1 8 0 2 h a v e a n i n p u t r a n g e t h a t i n c l u d e s both supply rails and an output that swings within 20mV of either supply rail to maximize the signal dynamic range in low supply applications. The LT1801/LT1802 maintain their performance for sup- plies from 2.3V to 12.6V and are specifi ed at 3V, 5V and ±5V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The LT1801 is available in the MS8, SO-8 and the 3mm × 3mm × 0.8mm dual fi ne pitch leadless package (DFN) with the standard dual op amp pinout. The LT1802 features the standard quad op amp confi guration and is available in the 14-pin plastic SO package. The LT1801/LT1802 can be used as plug-in replacements for many op amps to improve input/output range and performance. For a single version of these amplifi ers, see the LT1800 data sheet. n Gain Bandwidth Product: 80MHz n Input Common Mode Range Includes Both Rails n Output Swings Rail-to-Rail n Low Voltage Operation: Single or Split Supplies 2.3V to 12.6V n Low Quiescent Current: 2mA/Amplifi er Max n Input Offset Voltage: 350μV Max n Input Bias Current: 250nA Max n 3mm × 3mm × 0.8mm DFN Package n Large Output Current: 50mA Typ n Low Voltage Noise: 8.5nV/√ Hz Typ n Slew Rate: 25V/μs Typ n Common Mode Rejection: 105dB Typ n Power Supply Rejection: 97dB Typ n Open-Loop Gain: 85V/mV Typ n Operating Temperature Range: – 40°C to 85°C n L T1801 is Available in 8-Lead SO, MS8 and DFN Packages n L T1802 is Available in 14-Lead SO Package n Low Voltage, High Frequency Signal Processing n Driving A/D Converters n Rail-to-Rail Buffer Amplifi ers n Active Filters n Video Line Driver 1/2 LT1801 47pF 220pF VIN VS/2 909Ω 2.67k909Ω 1/2 LT1801 22pF VOUT470pF

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The inputs are protected by back-to-back diodes. If the differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA. It is not 100% tested. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefi nitely. Note 4: The LT1801C/LT1801I and LT1802C/LT1802I are guaranteed functional over the temperature range of – 40°C to 85°C. Note 5: The LT1801C/LT1802C are guaranteed to meet specifi ed performance from 0°C to 70°C. The LT1801C/LT1802C are designed, characterized and expected to meet specifi ed performance from –40°C to 85°C but are not tested or QA sampled at these temperatures. The LT1801I/LT1802I are guaranteed to meet specifi ed performance from –40°C to 85°C. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested. Note 9: Matching parameters are the difference between amplifi ers A and D and between B and C on the LT1802; between the two amplifi ers on the LT1801. Note 10: Thermal resistance (θ JA) varies with the amount of PC board metal connected to the package. The specifi ed values are for short traces connected to the leads. If desired, the thermal resistance can be substantially reduced by connecting Pin 4 of the SO-8 and MS8, Pin 11 of the SO-14 or the underside metal of the DD package to a larger metal area S– trace).

output voltage is at half of either supply voltage (or the maximum swing is less than 1/2 supply voltage). PDMAX is given by: P DMAX = (VS • ISMAX) + (VS/2)2/RL Example: An LT1801 in an SO-8 package operating on ±5V supplies and driving a 50Ω load, the worst-case power dissipation is given by: P = 0.17W If both amplifi ers are loaded simultaneously, then the total power dissipation is 0.34W. The maximum ambient temperature that the part is allowed to operate is: T A = TJ – (PDMAX • 190°C/W) Input Offset Voltage The offset voltage will change depending upon which input stage is active. The PNP input stage is active from the negative supply rail to 1.2V from the positive supply rail, then the NPN input stage is activated for the remain- ing input range up to the positive supply rail during which the PNP stage remains inactive. The offset voltage is typically less than 75μV in the range that the PNP input stage is active. Input Bias Current The LT1801/LT1802 employ a patent-pending technique to trim the input bias current to less than 250nA for the input common mode voltage of 0.2V above negative sup- ply rail to 1.2V of the positive rail. The low input offset voltage and low input bias current of the LT1801/LT1802 provide precision performance especially for high source impedance applications. Output The LT1801/LT1802 can deliver a large output current, so the short-circuit current limit is set around 50mA to prevent damage to the device. Attention must be paid to keep the junction temperature of the IC below the absolute maximum rating of 150°C (refer to the Power Dissipation section) when the output is continuously short circuited. The output of the amplifi er has reverse-biased diodes connected to each supply. If the output is forced beyond either supply, unlimited current will fl ow through these diodes. If the current is transient and limited to several hundred mA and the total supply voltage is less than 12.6V, the absolute maximum rating, no damage will occur to the device. Overdrive Protection When the input voltage exceeds the power supplies, two pairs of crossing diodes D1 to D4 will prevent the output from reversing polarity. If the input voltage exceeds either power supply by 700mV, diode D1/D2 or D3/D4 will turn on to keep the output at the proper polarity. For the phase reversal protection to perform properly, the input current m u s t b e l i m i t e d t o l e s s t h a n 1 0 m A . I f t h e a m p l i fi e r i s severely overdriven, an external resistor should be used to limit the overdrive current. The LT1801/LT1802’s input stages are also protected against a large differential input voltage of 1.4V or higher by a pair of back-back diodes D5/D8 to prevent the emit- ter-base breakdown of the input transistors. The current in these diodes should be limited to less than 10mA when they are active. The worst-case differential input voltage usually occurs when the input is driven while the output is shorted to ground in a unity gain confi guration. In ad- dition, the amplifi er is protected against ESD strikes up to 3kV on all pins by a pair of protection diodes on each pin that are connected to the power supplies as shown in Figure 1.
