DESCRIPTION
The PGA204 and PGA205 are low cost, general pur-
pose programmable-gain instrumentation amplifiers
offering excellent accuracy. Gains are digitally se-
lected: PGA204鈥?, 10, 100, 1000, and PGA205鈥?,
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
鹵40V
on the analog inputs without
damage.
The PGA204 and PGA205 are laser trimmed for very
low offset voltage (50碌V), drift (0.25碌V/擄C) and high
common-mode rejection (115dB at G=1000). They op-
erate with power supplies as low as
鹵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 鈥?0擄C to +85擄C temperature range.
