INA250 is a 36-V, Low-/High-Side, Bi-Directional, Zero-Drift, Current Sense Amplifier

This post is sponsored by Texas Instruments.

The INA250 is a voltage-output, current-sensing amplifier that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that  vary from 0 V to 36 V, independent of the supply voltage.

The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance, and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

The INA250 operates from a single 2.7-V to 36-V supply and draws a maximum of 300 µA of supply current. All INA250 gain versions are specified over the extended operating temperature range (–40°C to 125°C), and are available in a TSSOP-16 package.

The INA250 is available in four output voltage scales: 200 mV/A, 500 mV/A, 800 mV/A, and 2 V/A. It is fully tested and specified for continuous currents up to 10 amps at the maximum temperature of 125°C.
