AD7303BRZ-REEL7

AD7303 is a +2.7V to +5.5V, serial input, dual voltage output 8bit DAC. 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 30 MHz, 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 reference and to provide a synchronous loading facility for simultaneous update of the DAC outputs with a software LDAC function. Application includes portable battery powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators.
