DESCRIPTION
The INA2141 is a low power, dual 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 INA2141 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 per amplifier—ideal for battery
operated systems.
Packages are 16-pin plastic DIP, and SOL-16
surface-mount, specified for the –40°C to +85°C
temperature range.
