The INA141 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 (200kHz at G = 100).
Simple pin connections set an accurate gain of 10 or
100V/V without external resistors. Internal input pro-
tection can withstand up to
鹵40V
without damage.
The INA141 is laser trimmed for very low offset
voltage (50碌V), drift (0.5碌V/擄C) and high common-
mode rejection (117dB at G = 100). It operates with
power supplies as low as
鹵2.25V,
and quiescent
current is only 750碌A(chǔ)鈥攊deal for battery operated
systems.
The INA141 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.
