LTC1152 - Rail-to-Rail Input Rail-to-Rail Output Zero-Drift Op Amp

The LTC®1152 is a high performance, low power zero-drift op amp featuring an input stage that common modes to both power supply rails and an output stage that provides rail-to-rail swing, even into heavy loads. The wide in put common-mode range is achieved with a high frequency on-board charge pump. This technique eliminates the crossover distortion and limited CMRR imposed by competing technologies. The LTC1152 is a C-Load (TM) of amp, enabling it to drive any capacitive load. The LTC1152 shares the excellent DC performance specs of LTC’s other zero-drift amplifiers. Typical offset voltage is 1µVand typical offsetdrift is 10nV/°C.CMRR and PSRR are 130dB and 120dB and open-loop gain is 130dB. Input noise voltage is 2µVP-P from 0.1Hz to 10Hz. Gain-bandwidth product is 0.7MHz and slew rate is 0.5V/µs, all with product is 0.7MHz and slew rate is 0.5V/µs, all with supply current of 3.0mA max over temperature. The LTC1152 also includes a shutdown feature which drops supply current to 1µA and puts the output stage in a high impedance state. 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.
