Analog Devices Inc.

The AD8418A is a high voltage, high resolution current shunt amplifier. It features an initial gain of 20 V/V, with a maximum ?0.15% gain error over the entire temperature range. The buffered output voltage directly interfaces with any typical converter. The AD8418A offers excellent input common-mode rejection from ?2 V to +70 V. The AD8418A 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 AD8418A offers breakthrough performance throughout the ?40?C to +150?C temperature range. It features a zero drift core, which leads to a typical offset drift of 0.1 ?V/?C throughout the operating temperature range and the common-mode voltage range. The AD8418A is qualified for automotive applications. The device includes EMI filters and patented circuitry to enable output accuracy with pulse-width modulation (PWM) type input common-mode voltages. The typical input offset voltage is ?100 ?V. The AD8418A is offered in an 8-lead MSOP and an 8-lead SOIC_N package with a 10-lead MSOP pinout option engineered for failure mode and effects analysis (FMEA).Applications High-side current sensing in Motor controls Solenoid controls Power management Low-side current sensing Diagnostic protection
