Product Summary
The AD7302BRUZ is a dual, 8-bit voltage out DAC that operates from a single +2.7 V to +5.5 V supply. Its on-chip precision output buffers allow the DAC outputs to swing rail to rail. The AD7302 has a parallel microprocessor and DSP-compatible interface with high speed registers and double buffered interface logic. Data is loaded to the registers on the rising edge of CS or WR and the A/B pin selects either DAC A or DAC B. The applications of the AD7302BRUZ include Portable Battery Powered Instruments, Digital Gain and Offset Adjustment, Programmable Voltage and Current Sources, Programmable Attenuators.
