The AD8410 is a high voltage, high resolution, and high bandwidth current shunt amplifier. It features an initial gain of 20 V/V, with a 2.0 MHz bandwidth with a maximum ±0.3% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8410 offers excellent input common-mode rejection from −2 V to +70 V. The AD8410 performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, power management, and solenoid control.

The AD8410 offers breakthrough performance throughout the −40°C to +150°C temperature range. It features a in package trim core, which leads to a typical offset drift of 1.0 µV/°C throughout the operating temperature range and the common-mode voltage range. The AD8410 is qualified for automotive applications. The device includes patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages. The typical input offset voltage is ±200 µV. The AD8410 is offered in 8-lead MSOP or SOIC packages.
