The LTC
1050 is a high performance, low cost zero-drift
operational amplifier. The unique achievement of the
LTC1050 is that it integrates on-chip the two sample-and-
hold capacitors usually required externally by other chop-
per amplifiers. Further, the LTC1050 offers better com-
bined overall DC and AC performance than is available
from other chopper stabilized amplifiers with or without
internal sample-and-hold capacitors.
The LTC1050 has an offset voltage of 0.5V, drift of
0.01V/°C, DC to 10Hz, input noise voltage of 1.6VP-P
and a typical voltage gain of 160dB. The slew rate of 4V/s
and a gain bandwidth product of 2.5MHz are achieved with
only 1mA of supply current.
Overload recovery times from positive and negative satu-
ration conditions are 1.5ms and 3ms respectively, which
represents an improvement of about 100 times over chop-
per amplifiers using external capacitors. Pin 5 is an optional
external clock input, useful for synchronization purposes.
The LTC1050 is available in standard 8-pin metal can,
plastic and ceramic dual-in-line packages as well as an
SO-8 package. The LTC1050 can be an improved plug-in
replacement for most standard op amps.
