both power supply rails and an output stage that provides ■ No External Components Required rail-to-rail swing, even into heavy loads. The wide input ■ Input Offset Voltage: 10µV Max common-mode range is achieved with a high frequency ■ Input Offset Drift: 100nV/°C Max on-board charge pump. This technique eliminates the ■ Minimum CMRR: 115dB crossover distortion and limited CMRR imposed by com- ■ Supply Current: 3.0mA Max peting technologies. The LTC1152 is a C-LoadTM of amp, ■ Shutdown Pin Drops Supply Current to 5µA Max enabling it to drive any capacitive load. ■ Output Configurable to Drive Any Capacitive Load The LTC1152 shares the excellent DC performance specs ■ Operates from 2.7V to 14V Total Supply Voltage of LTC’s other zero-drift amplifiers.

are 130dB and 120dB and open-loop gain is 130dB. Input noise voltage is 2µV ■ Rail-to-Rail Amplifiers and Buffers P-P from 0.1Hz to 10Hz. Gain-band- width product is 0.7MHz and slew rate is 0.5V/µs, all with ■ High Resolution Data Acquisition Systems supply current of 3.0mA max over temperature. The ■ Supply Current Sensing in Either Rail LTC1152 also includes a shutdown feature which drops ■ Low Supply Voltage Transducer Amplifiers supply current to 1µA and puts the output stage in a high ■ High Accuracy Instrumentation impedance state. ■ Single Negative Supply Operation The LTC1152 is available in 8-pin PDIP and 8-pin SO packages and uses the standard op amp pinout, allowing it to be a plug-in replacement for many standard op amps. , LTC and LT are registered trademarks of Linear Technology Corporation.
