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 (50
μ
V), drift (0.5
μ
V/
°
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 700
μ
A 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.
