The AD7302 is a dual, 8-bit voltage out DAC that operatesfrom a single +2.7 V to +5.5 V supply. Its on-chip precisionoutput buffers allow the DAC outputs to swing rail to rail. TheAD7302 has a parallel microprocessor and DSP-compatibleinterface with high speed registers and double buffered interfacelogic. Data is loaded to the registers on the rising edge of CS orWR and the A/B pin selects either DAC A or DAC B.
