INA216 - 5V, Low-Power, High-side, Zero-Drift, Voltage Output Current Sense Amp in WCSP package

Updated : 2020-01-09 14:22:53
Description

The INA216 is a high-side voltage output current shunt monitor that can sense drops across shunts at common-mode voltages from +1.8V to +5.5V. Four fixed gains are available: 25V/V, 50V/V, 100V/V, and 200V/V. The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10mV full-scale, or with wide dynamic ranges of over 1000:1.

These devices operate from a single +1.8V to +5.5V power supply, drawing a maximum of 25µA of supply current. The INA216 series are specified over the temperature range of –40°C to +125°C, and offered in a chip-scale package.
