gain instrumentation amplifiers that are ideally suited
for data acquisition systems.
The PGA206 and PGA207鈥檚 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
鹵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 鈥?0擄C to +85擄C operation.
