DESCRIPTION
The INA2128 is a dual, 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).
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to ±40V
without damage.
The INA2128 is laser trimmed for very low offset
voltage (50µV), drift (0.5µV/°C) and high common-
mode rejection (120dB at G ≥ 100). It operates with
power supplies as low as ±2.25V, and quiescent current
is only 700µA per IA—ideal for battery operated and
multiple-channel systems.
The INA2128 is available in 16-pin plastic DIP, and
SOL-16 surface-mount packages, specified for the
–40°C to +85°C temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
