INA125P Instrumentation Amplifier With Precision Voltage Reference

RBD-0276

The INA125 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 10,000. The INA125 is laser-trimmed for low offset voltage (250µV), low offset drift (2µV/°C), and high common-mode rejection (100dB at G = 100). It operates on either single (+2.7V to +36V) or dual (±1.35V to ±18V) supplies.

Description

The INA125 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 10,000. The INA125 is laser-trimmed for low offset voltage (250µV), low offset drift (2µV/°C), and high common-mode rejection (100dB at G = 100). It operates on either single (+2.7V to +36V) or dual (±1.35V to ±18V) supplies.

The voltage reference is externally adjustable with pin-selectable voltages of 2.5V, 5V, or 10V, making it compatible with various transducers. The reference voltage is accurate to ±0.5% (max) with ±35ppm/°C drift (max). A sleep mode allows for shutdown and duty cycle operation to save power.

The INA125 is available in 16-pin plastic DIP and SO-16 surface-mount packages and is specified for the industrial temperature range of –40°C to +85°C.
