Overview
The AD7399BRU is a quad, serial-input 10-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This monolithic DAC is built using the robust CBCMOS process, offering low cost and ease of use in both single and dual-supply systems. It operates from a single 3 V to 5 V supply or a dual ±5 V supply, making it versatile for various applications. The device features a 3-wire, SPI-compatible interface and includes double-buffered registers for simultaneous update of all DAC outputs. An internal power-on reset and an external asynchronous reset ensure that the output voltage is set to zero at system turn-on and during reset, respectively.
