Overview
The AD5554BRSZ is a quad, 14-bit, current-output, serial-input digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This component is designed to operate within a supply voltage range of 2.7 V to 5.5 V, making it versatile for various applications. The AD5554BRSZ features a double-buffered serial data interface, which is compatible with SPI and microcontroller interfaces, using serial data in (SDI), chip select (CS), and clock (CLK) signals. It also includes a serial data out pin (SDO) for daisy-chaining multiple packages. The device is packaged in a compact 28-lead SSOP, making it suitable for space-constrained designs.
