描述 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.
