Overview
The INA159AIDGKT is a high-speed, precision difference amplifier produced by Texas Instruments. This component is designed to interface ±10V signals to single-supply analog-to-digital converters (ADCs), particularly those operating on a single +5V supply. The INA159AIDGKT consists of a precision op amp with a precision resistor network, providing accurate gain and high common-mode rejection. It operates on a single or split supply from +1.8V to +5.5V and is specified for operation over the extended industrial temperature range of -40°C to +125°C.
