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.
