DESCRIPTION

The PGA206 and PGA207 are digitally programmable

gain instrumentation amplifiers that are ideally suited

for data acquisition systems.

The PGA206 and PGA207’s fast settling time allows

multiplexed input channels for excellent system effi-

ciency. FET inputs eliminate I

errors due to analog

multiplexer series resistance.

Gains are selected by two CMOS/TTL-compatible

address lines. Analog inputs are internally protected

for overloads up to ±40V, even with the power sup-

plies off. The PGA206 and PGA207 are laser-trimmed

for low offset voltage and low drift.

The PGA206 and PGA207 are available in 16-pin

plastic DIP and SOL-16 surface-mount packages. Both

are specified for –40°C to +85°C operation.
