MAX9923 Product details

Description

MAX9922/MAX9923 The MAX9922/MAX9923 ultra-precision, high-side current-sense amplifiers feature ultra-low offset voltage (VOS) of 25µV (max) and laser-trimmed gain accuracy better than 0.5%.The combination of low VOS and highgain accuracy allows precise current measurements even at very small sense voltages.The MAX9922/MAX9923 are capable of both unidirectional and bidirectional operation.For unidirectional operation, connect REF to GND.For bidirectional operation, connect REF to VDD/2.
