AD8219BRMZ-RL

Overview

The AD8219BRMZ-RL is a high-voltage, unidirectional current shunt amplifier manufactured by Analog Devices Inc. It features a fixed gain of 60 V/V with a maximum gain error of 0.3% across the operating temperature range. The device operates within a supply voltage range of 4 V to 80 V and consumes a typical quiescent current of 800 uA. Key electrical specifications include a common-mode rejection ratio (CMRR) of 90 dB, an input bias current of 130 uA, and an input offset voltage of 200 uV. The component provides a bandwidth of 500 kHz and is housed in an 8-pin MSOP package.

Feature Summary

• High-voltage operation supporting up to 80 V common-mode signals
• Fixed internal gain of 60 V/V for simplified circuit design
• Zero-drift architecture minimizing offset voltage drift over temperature

Applications

• High-side current sensing in industrial motor drives
• Battery management systems requiring precise charge monitoring
• Overcurrent protection circuits in power distribution units

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required reel packaging configuration. Request batch-specific datasheets to validate performance parameters against application requirements. Ensure storage conditions comply with moisture sensitivity levels defined in the manufacturer's handling guidelines.

Selection Notes

Select this component when high common-mode voltage tolerance exceeds standard operational amplifier capabilities. The fixed 60 V/V gain eliminates external resistor networks, reducing board space and calibration complexity. Consider the zero-drift technology for applications demanding high accuracy without frequent recalibration. Evaluate the 800 uA quiescent current against system power budget constraints.
