The INA118 is a low power, general purpose instru-
mentation amplifier offering excellent accuracy. Its
versatile 3-op amp design and small size make it ideal
for a wide range of applications. Current-feedback
input circuitry provides wide bandwidth even at high
gain (70kHz at G = 100).
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to
鹵40V
without damage.
The INA118 is laser trimmed for very low offset voltage
(50碌V), drift (0.5碌V/擄C) and high common-mode re-
jection (110dB at G = 1000). It operates with power
supplies as low as
鹵1.35V,
and quiescent current is only
350碌A(chǔ)鈥攊deal for battery operated systems.
The INA118 is available in 8-pin plastic DIP,
and SO-8 surface-mount packages, specified for
the 鈥?0擄C to +85擄C temperature range.
