AD8211WYRJZ-R7

The AD8211WYRJZ-R7 from Analog Devices is a high-voltage, precision current shunt amplifier designed for unidirectional current measurements. It features a fixed gain of 20 V/V with a typical gain error of ±0.35% across the entire temperature range. The device boasts a high common-mode input voltage range from -2 V to +65 V and a continuous input voltage range from -3 V to +68 V, making it suitable for demanding applications.

With excellent AC and DC performance, including a typical offset drift of 5 µV/°C and a typical gain vs. temperature drift of -13 ppm/°C, the AD8211WYRJZ-R7 ensures reliable measurements. It also provides a typical common-mode rejection ratio (CMRR) of 120 dB at DC. The buffered output voltage is compatible with typical converters.

This current monitor IC is qualified for automotive applications and is offered in a compact 5-lead SOT-23-5 package (SC-74A, SOT-753). It operates within a wide temperature range of -40°C to +125°C. The ±4000 V HBM ESD rating adds to its robustness.

Key applications include high-side current sensing in motor controls, transmission controls, engine management systems, suspension controls, vehicle dynamic controls, and DC-to-DC converters.
