ESCRIPTIO
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 1µV and typical offset drift is 10nV/°C. CMRR and PSRR
are 130dB and 120dB and open-loop gain is 130dB. Input
noise voltage is 2µV
P-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 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.

parts.
Note 4: All output swing measurements are taken with the load resistor
connected from output to ground. For single supply tests, only the positive
swing is specified (negative swing will be 0V due to the pull-down effect of
the load resistor). For dual supply operation, both positive and negative
swing are specified.
The
● denotes specifications which apply over the full operating
temperature range.
Note 1: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels during automated testing.
Note 2: At T ≤ 0°C these parameters are guaranteed by design and not
tested.
Note 3: 0.1Hz to 10Hz noise is specified DC coupled in a 10-sec window;
0.1Hz to 1Hz noise is specified in a 100-sec window with an RC highpass
