Texas Instruments INA117P Differential Amplifier 200kHz

The Texas Instruments INA117P Differential Amplifier is a unity-gain difference amplifier with a 200kHz bandwidth, designed to measure small differential voltages in the presence of high common-mode signals.

Overview

This single monolithic IC integrates a high-precision operational amplifier with a thin-film resistor network. Its inputs offer a common-mode input voltage range of ±200V and are protected against momentary common-mode or differential overloads up to ±500V, enabling measurements in conditions where many standard amplifiers would not operate accurately. It can serve as an alternative to isolation amplifiers in designs where galvanic isolation is not strictly required, which removes the need for isolated power supplies in suitable circuits.

Key Features

• Maximum nonlinearity of 0.001%
• Maximum gain error of 0.02%
• Minimum common-mode rejection ratio (CMRR) of 86dB
• Gain bandwidth product of 200kHz
• Slew rate of 2.6V/µs

Applications

The INA117P is suited to power management solutions, industrial automation, and precision process control systems, as well as accurate differential signal conditioning. Its through-hole 8-pin DIP package supports integration into prototype boards and final designs.

Specifications

• Supply voltage range of ±5V to ±18V
• Input offset voltage of 1mV
• Single amplifier
• Through-hole mounting
