Product Summary

The INA129U is a low power, general purpose instrumentation amplifier. It is laser trimmed for very low offset voltage (50μV), drift (0.5μV/℃) and high common-mode rejection (120dB at G ≥ 100). The INA129U operates with power supplies as low as ±2.25V, and quiescent current is only 700μA-ideal for battery operated systems. Internal input protection can withstand up to ±40V without damage. The INA129U is available in 8-pin plastic DIP, and SO-8 surface-mount packages, specified for the -40℃ to +85℃ temperature range. The applications of it include bridge amplifier, thermocouple amplifier, rtd sensor amplifier, medical instrumentation, data acquisition.
