DESCRIPTION
The INA128 and INA129 are low power, general
purpose instrumentation amplifiers offering excellent
accuracy. Their versatile 3-op amp design and small
size make them ideal for a wide range of applications.
Current-feedback input circuitry provides wide band-
width even at high gain (200kHz at G = 100).
A single external resistor sets any gain from 1 to
10,000. INA128 provides an industry standard gain
equation; INA129’s gain equation is compatible with
the AD620.
The INA128/INA129 is laser trimmed for very low
offset voltage (50
μ
V), drift (0.5
μ
V/
°
C) and high com-
mon-mode rejection (120dB at G
≥
100). It operates
with power supplies as low as
±
2.25V, and quiescent
current is only 700
μ
A—ideal for battery operated
systems. Internal input protection can withstand up to
±
40V without damage.
The INA128/INA129 is available in 8-pin plastic
DIP, and SO-8 surface-mount packages, specified for
the –40
°
C to +85
°
C temperature range. The INA128
is also available in dual configuration, the INA2128.
