INA125U .

The INA125U is a low power high accuracy Instrumentation Amplifier with a precision voltage reference. It provides complete bridge excitation and precision differential-input amplification on a single integrated circuit. A single external resistor sets any gain from 4 to 10000. The INA125 is laser-trimmed for low offset voltage (250mV), low offset drift (2μV/°C) and high common-mode rejection (100dB at G=100). It operates on single (+2.7 to +36V). The reference voltage is accurate to ±0.5% (maximum) with ±35ppm/°C drift (maximum). Sleep mode allows shutdown and duty cycle operation to save power.
