Data Sheet  
FEATURES  
GENERAL DESCRIPTION  
Typical 0.1 µV/°C offset drift  
The AD8417 is a high voltage, high resolution current shunt  
amplifier. It features an initial gain of 60 V/V, with a maximum  
0.3% gain error over the entire temperature range. The  
buffered output voltage directly interfaces with any typical  
converter. The AD8417 offers excellent input common-mode  
rejection from −2 V to +70 V. The AD8417 performs bidirectional  
current measurements across a shunt resistor in a variety of  
automotive and industrial applications, including motor control,  
power management, and solenoid control.  
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 continuous  
−4 V to +85 V survival  
Initial gain = 60 V/V  
Wide operating temperature range: −40°C to +125°C  
Bidirectional operation  
The AD8417 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 AD8417 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 200 µV. The AD8417 is offered in 8-lead MSOP and SOIC  
packages.  
Available in 8-lead SOIC and 8-lead MSOP  
Common-mode rejection ratio (CMRR): 86 dB, dc to 10 kHz  
Qualified for automotive applications
