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 bandwidth
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 (50mV), drift (0.5mV/°C) and high common-
mode rejection (120dB at G ³ 100). It operates
with power supplies as low as ±2.25V, and quiescent
current is only 700mA—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.
