The LTC
1150 is a high-voltage, high-performance
zero-drift operational amplifier. The two sample-and-hold
capacitors usually required externally by other chopper
amplifiers are integrated on-chip. Further, LTC’s propri-
etary high-voltage CMOS structures allow the LTC1150 to
operate at up to 32V total supply voltage.
The LTC1150 has an offset voltage of 0.5V, drift of
0.01V/°C, 0.1Hz to 10Hz input noise voltage of 1.8VP-P
and a typical voltage gain of 180dB. The slew rate of 3V/s
and a gain bandwidth product of 2.5MHz are achieved with
0.8mA of supply current. Overload recovery times from
positive and negative saturation conditions are 3ms and
20ms, respectively.
For applications demanding low power consumption,
Pin 1 can be used to program the supply current. Pin 5 is
an optional AC-coupled clock input, useful for
synchronization.
The LTC1150 is available in standard 8-lead, plastic dual-
in-line package, as well as an 8-lead SO package. The
LTC1150 can be a plug-in replacement for most standard
bipolar op amps with significant improvement in DC
performance.
