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 (50
μ
V), drift (0.25
μ
V/
°
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.
