INA125 Instrumentation Amplifiers with Precision Voltage Reference

Texas Instruments offers its INA125 instrumentation amplifiers with precision voltage reference for pressure and temperature bridge amplifier applications

Texas Instruments' INA125 are low power, high accuracy instrumentation amplifiers with a precision voltage reference. They provide 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 are laser-trimmed for low offset voltage (250 µV), low offset drift (2 µV/¡ãC), and high common-mode rejection (100 dB at G = 100). They operate on single (2.7 V to 36 V) or dual (¡À1.35 V to ¡À18 V) supplies. The voltage reference is externally adjustable with pin-selectable voltages of 2.5 V, 5 V, or 10 V, allowing use with a variety of transducers. The reference voltage is accurate to ¡À0.5% (max) with ¡À35 ppm/¡ãC drift (max). Sleep mode allows shutdown and duty cycle operation to save power. The INA125 are available in 16-pin plastic DIP and SO-16 surface-mount packages and are specified for the -40¡ãC to 85¡ãC industrial temperature range.
