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 in-
puts. The PGA103 is ideal for systems that must
handle wide dynamic range signals.
The PGA103’s high speed circuitry provides fast set-
tling time, even at G=100 (8µs 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.
