## Description

The Texas Instruments INA168NA is a high-side, unipolar current shunt monitor. It is designed to measure current by converting a differential input voltage across a shunt resistor into a current output. This current can then be converted back to a voltage using an external load resistor, allowing for adjustable gain.

The INA168NA operates with a wide input common-mode voltage range from 2.7V to 60V, independent of the supply voltage. This feature enables its use in various applications where high-side current monitoring is required. The device boasts a low quiescent current of only 25 µA typical, minimizing power consumption and reducing measurement error when placed in series with the current path.

Key electrical specifications include a bandwidth of 32 kHz, a maximum input offset voltage of 1000 µV, and a gain error of 2%. The operating temperature range is from -40°C to 125°C, making it suitable for demanding environments. The INA168NA is available in a compact 5-pin SOT-23 package, ideal for space-constrained designs.

This current sense amplifier is well-suited for applications such as battery management, power monitoring, and current control systems where accurate and reliable current measurement is critical.
