The AD8213 is a dual-channel, precision current sense amplifier. It features a set gain of 20 V/V, with excellent ac and dc performance. It can be used in high-side current sensing, motor controls, transmission controls, diesel injection controls, engine management, suspension controls, vehicle dynamic controls, and DC-to-DC converters.
The AD8213 is a dual‑channel precision current‑sense amplifier offering a fixed gain of 20 V/V and excellent common‑mode rejection from –2 V to +65 V. It includes buffered outputs, low‑pass filter pins, and operates over a temperature range of –40 °C to +125 °C in a compact 10‑lead MSOP package.
Typical applications include high‑side current sensing for motor control, transmission control, diesel injection, engine management, suspension systems, DC‑DC converters and other automotive or industrial power‑management circuits. The device provides high‑voltage ESD protection (+4000 V HBM) and can handle supply voltages up to 12.5 V while maintaining low offset and drift characteristics.
