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_B 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.
