Bidirectional, Zero Drift,Current Sense AmplifierData SheetAD8418FEATURESGENERAL DESCRIPTIONTypical 0.1 µV/°C offset drift The AD8418 is a high voltage, high resolution current shunt Maximum ±400 µV voltage offset over full temperature range amplifier. It features an initial gain of 20 V/V, with a maximum 2.7 V to 5.5 V power supply operating range ±0.15% gain error over the entire temperature range. The Electromagnetic interference (EMI) filters Included buffered output voltage directly interfaces with any typical High common-mode input voltage range converter. The AD8418 offers excel ent input common-mode −2 V to +70 V operating rejection from −2 V to +70 V. The AD8418 performs bidirectional −4 V to +85 V survival current measurements across a shunt resistor in a variety of Initial gain = 20 V/V automotive and industrial applications, including motor Wide operating temperature range: −40°C to +125°C control, battery management, and solenoid control. Bidirectional operation Available in 8-lead SOIC and 8-lead MSOP The AD8418 offers breakthrough performance throughout the Common-mode rejection ratio (CMRR): 86 dB, dc to 10 kHz −40°C to +125°C temperature range. It features a zero drift core, Qualified for automotive applications which leads to a typical offset drift of 0.1 µV/°C throughout the
