Overview
The AD5305BRMZ is a quad 8-bit 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 designed for low power consumption, typically 500 μA at 3 V and 600 μA at 5 V. The device features a 2-wire serial interface compatible with I2C and SMBus protocols, allowing for multiple devices to be connected on the same bus. The AD5305BRMZ is housed in a 10-lead MSOP or TFSOP package, making it suitable for a variety of applications requiring precise voltage output control.
