AD8417BRMZ-RL

The AD8417 is a high-voltage, high-resolution current sense amplifier. The initial gain is set at 60 V/V, with a maximum gain error of ±0.3% over the full temperature range. The buffered output voltage can connect directly to any typical converter. With input common-mode voltage ranging from -2 V to +70 V, the AD8417 delivers excellent input CMR performance; it supports bidirectional current measurement across a shunt resistor, making it suitable for a wide range of automotive and industrial applications, including motor control, power management, and solenoid control. The AD8417 delivers exceptional performance across the full temperature range of -40°C to +125°C. Its zero-drift core achieves a typical offset drift of 0.1 μV/°C over the full operating temperature and common-mode voltage range. The AD8417 is qualified for automotive applications. The device integrates an EMI filter and patented circuitry for high output accuracy under PWM-type input common-mode voltages. The typical input offset voltage is ±200 μV. The AD8417 is available in 8-lead MSOP and SOIC packages.
