GENERAL DESCRIPTION
The ADM1191 is an integrated current sense amplifier that offers digital current and voltage monitoring via an on-chip 12-bit analog-to-digital converter (ADC), communicated through an I2C® interface.
An internal current sense amplifier measures voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.
A 12-bit ADC can measure the curren.
