AD7303BNZ

AD7303BNZ is a dual, 8bit voltage out DAC that operates from a single +2.7V to +5.5V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. This device uses a versatile 3-wire serial interface that operates at clock rates upto 30MHz and is compatible with QSPI, SPI, microwire and digital signal processor interface standards. The serial input register is sixteen bits wide; 8 bits act as data bits for the DACs, and the remaining eight bits make up a control register. The on-chip control register is used to address the relevant DAC, to power down the complete device or an individual DAC, to select internal or external references, and to provide a synchronous loading facility for simultaneous update of the DAC outputs with a software LDAC function. It is used in applications such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
