AD7303BRZ, 8-битный ЦАП с последовательным входом [SO-8]

The AD7303BRZ is a dual 8-bit voltage out Digital-to-analog Converter (DAC) operates from a single 2.7 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 up to 30MHz and is compatible with QSPI, SPI, MICROWIRE and digital signal processor interface standards. 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. The low power consumption of this part makes it ideally suited to portable battery operated equipment. The power consumption is 7.5mW maximum at 3V, reducing to less than 3µW in full power-down mode.
