Voltage current monitor ZXCT21 series

The ZXCT21x series are high-precision current-shunt monitor with different choices of gain options to measure low-voltage drop (10mV) across a small shunt resistor with minimal error. This enables high accuracy of large current measurement and reduces a power loss caused by the measurement at common-mode voltages from -0.3V to 26V. OUT pin is a voltage proportional to the load current. It can then be processed with an ADC. There are six fixed gains available: 50, 75, 100, 200, 500, and 1000 V/V respectively. This device is designed with zero-drift architecture and is manufactured by post trim technology to achieve low offset voltage, low gain drift and low gain error among full temperature range for precise measurement. The ZXCT21x operates from a single 2.7V to 26V power supply with a maximum of 100μA of supply current from -40°C to +125°C, and is offered in SOT363 and U-QFN1418-10 package.
