The AD7304BRUZ is a quad 8-bit Digital-to-analog Converter (DAC) operates from a single 3 to 5V supply or ±5V supplies. The reference input range includes both supply rails allowing for positive or negative full-scale output voltages. Operation is guaranteed over the supply voltage range of 2.7 to 5.5V, consuming less than 9mW from a 3V supply. The full-scale voltage output is determined by the external reference input voltage applied. It is doubled-buffered serial data interface offers high speed, 3-wire, SPI? and microcontroller-compatible inputs using data in (SDI), clock (CLK) and chip select (CS) pins. Additionally an internal power-on reset sets the output to zero scale. The double-buffered architecture allows all four input registers to be preloaded with new values, followed by an LDAC control strobe that copies all the new data into the DAC registers, thereby updating the analog output values.
