The LTC

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 0.5µV, drift of

and a typical voltage gain of 180dB. The slew rate of 3V/µs

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.
