AD8417WHRMZ

The AD8417 is a high voltage, high resolution current sense amplifier. It features an initial gain of 60 V/V, with a maximum ±0.3% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8417 offers excellent input common-mode rejection from -2 V to +70 V. The AD8417 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 AD8417 offers breakthrough performance throughout the -40°C to +150°C temperature range (AD8417WH). It features a zero drift core, which leads to a typical offset drift of 0.1 μV/°C throughout the operating temperature range and the common - mode voltage range. The AD8417 is qualified for automotive applications. The device includes electromagnetic interference (EMI) filters and patented (U.S. Patent 8,624,668 B2) circuitry to enable output accuracy with pulse - width modulation (PWM) type input common - mode voltages. The typical input offset voltage is ±200 μV. The AD8417 is offered in 8 - lead MSOP and 8 - lead SOIC_N, along with a 10 - lead MSOP pinout option engineered for failure mode and effects analysis (FMEA).
