General Description
INA128 General 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 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 (50V), drift (0.5V/) and high common- mode rejection (120dB at G 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 to +85 temperature range. The INA128 is also available in dual configuration, the INA2128.
