Overview
The AD5315ARMZ-REEL7 is a quad, 10-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This integrated circuit is designed for low power consumption and compact design, making it highly suitable for portable battery-operated equipment. It operates from a single 2.5V to 5.5V supply, consuming 500μA at 3V, and features a 2-wire (I²C-compatible) serial interface. The device includes on-chip rail-to-rail output buffer amplifiers and supports simultaneous update of all DAC outputs using the LDAC function. Additionally, it has a power-on reset circuit and a software clear function to reset all input and DAC registers to 0V.
