DESCRIPTIO

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 input

common-mode range is achieved with a high frequency

on-board charge pump. This technique eliminates the

crossover distortion and limited CMRR imposed by com-

peting 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 1

µV and typical offset drift is 10nV/°C. CMRR and PSRR

are 130dB and 120dB and open-loop gain is 130dB. Input

noise voltage is 2

µVP-P from 0.1Hz to 10Hz. Gain-band-

width 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 1

µA 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.
