ADM1294-1BACPZ

Overview

The ADM1294-1BACPZ is a high-accuracy, single-phase digital power monitor integrated circuit manufactured by Analog Devices Inc. It features an integrated shunt regulator for low-side supply monitoring across wide voltage ranges. The device utilizes an on-chip 12-bit analog-to-digital converter (ADC) to provide precise digital measurements of current, voltage, and power. Communication with host systems is facilitated through a PMBus-compatible I2C interface. The component is housed in a 48-lead LFCSP package.
