Analog Devices AD8219 Current Shunt Amplifier Datasheet
The AD8219 is a high‑voltage, high‑resolution current shunt amplifier featuring a fixed gain of 60 V/V, a wide common‑mode voltage range of 4 V to 80 V, and operation across –40 °C to +125 °C. It includes a zero‑drift core that provides typical offset drift of ±100 nV/°C and a buffered output that can directly interface with converters.
Typical applications include high‑side current sensing for telecom (48 V), power‑management circuits, base‑station bias control, and motor‑control systems. The device is supplied in an 8‑lead MSOP package and offers robust ESD protection, wide supply range (4 V‑80 V), and low quiescent current.
