DESCRIPTION

The PGA103 is a programmable-gain amplifier for

general purpose applications. Gains of 1, 10, or 100 are

digitally selected by two CMOS/TTL-compatible inputs.

The PGA103 is ideal for systems that must

handle wide dynamic range signals.

The PGA103’s high speed circuitry provides fast settling

time, even at G=100 (8ms to 0.01%). Bandwidth

is 250kHz at G=100, yet quiescent current is only

2.6mA. It operates from ±4.5V to ±18V power

supplies.

The PGA103 is available in 8-pin plastic DIP and

SO-8 surface-mount packages, specified for the –40°C

to +85°C temperature range.
