The INA141 is a low power, general purpose instrumentation
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 protection
can withstand up to ±40V without damage.
The INA141 is laser trimmed for very low offset
voltage (50mV), drift (0.5mV/°C) and high commonmode
rejection (117dB at G = 100). It operates with
power supplies as low as ±2.25V, and quiescent
current is only 750mA—ideal for battery operated
systems.
The INA141 is available in 8-pin plastic DIP, and
SO-8 surface-mount packages, specified for the –40°C
to +85°C temperature range.
