DESCRIPTION
The PGA204 and PGA205 are low cost, general pur-
pose programmable-gain instrumentation amplifiers
offering excellent accuracy. Gains are digitally se-
lected: PGA204—1, 10, 100, 1000, and PGA205—1,
2, 4, 8V/V. The precision and versatility, and low cost
of the PGA204 and PGA205 make them ideal for a
wide range of applications.
Gain is selected by two TTL or CMOS-compatible
address lines, A
0
and A
1
. Internal input protection can
withstand up to
±40V
on the analog inputs without
damage.
The PGA204 and PGA205 are laser trimmed for very
low offset voltage (50µV), drift (0.25µV/°C) and high
common-mode rejection (115dB at G=1000). They op-
erate with power supplies as low as
±4.5V,
allowing use
in battery operated systems. Quiescent current is 5mA.
The PGA204 and PGA205 are available in 16-pin
plastic DIP, and SOL-16 surface-mount packages, speci-
fied for the –40°C to +85°C temperature range.

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
NC: No Internal Connection.
