Overview
The AD5315ARMZ is a 10-bit quad buffered voltage output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This component operates from a single 2.5 V to 5.5 V supply and is housed in a 10-lead MSOP package. It is part of the AD5305/AD5315/AD5325 family, which includes 8-, 10-, and 12-bit resolutions, respectively. The AD5315ARMZ is designed for low power consumption, using 500 μA at 3 V, and features a 2-wire serial interface compatible with I²C and SMBus protocols up to 400 kHz clock rates.
