Overview
Data Sheet FEATURES Typical 0.
1 µV/°C offset drift Maximum ±400 µV voltage offset over full temperature range 2.
7 V to 5.
5 V power supply operating range Electromagnetic interference (EMI) filters Included High common-mode input voltage range −2 V to +70 V operating −4 V to +85 V survival Initial gain = 20 V/V Wide operating temperature range: −40°C to +125°C Bidirectional operation Available in 8-lead SOIC and 8-lead MSOP Common-mode rejection ratio (CMRR): 86 dB, dc to 10 kHz Qualified for automotive applications Bidirectional, Zero Drift, Current Sense Amplifier AD8418 GENERAL DESCRIPTION The AD8418 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 AD8418 offers excellent input common-mode rejection from −2 V to +70 V.
The AD8418 performs bidirectional current measurements across a shunt resistor in a variety of automotive and industrial applications, including motor control, battery management, and solenoid control.
The AD8418 offers breakthrough performance throughout the −40°C to +125°C temperature range.
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 AD8418 is fully qualified for automotive applications and 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 ±200 µV.
The AD8418 is offered in 8-lead MSOP and SOIC packages.
