Bidirectional, Zero Drift,
Current Sense Amplifier
AD8418 Data Sheet
FEATURES GENERAL DESCRIPTION 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 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 …
