Product Introduction

Overview

The INA201AID from Texas Instruments is a high-side current-shunt monitor with a voltage output and an integrated comparator. This device is part of the INA20x series, which includes the INA200, INA201, and INA202, each offering different gain options. The INA201AID specifically provides a gain of 50 V/V. It is designed to sense voltage drops across shunts at common-mode voltages ranging from –16 V to 80 V, making it versatile for various high-side current sensing applications. The device operates from a single 2.7-V to 18-V supply and is available in SOIC-8 and VSSOP-8 packages, ensuring a compact footprint while maintaining high performance over an extended operating temperature range of –40°C to +125°C.
