GENERAL DESCRIPTION AD7302BRUZ

The AD7302 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.

PRODUCT HIGHLIGHTS

1.␣ Low Power, Single Supply Operation. This part operates

from a single +2.7 V to +5.5 V supply and typically consumes

15 mW at 5 V, making it ideal for battery powered applications.

2.␣ The on-chip output buffer amplifiers allow the outputs of the

DACs to swing rail to rail with a settling time of typically 1.2 μs.

3.␣ Internal or external reference capability.

4.␣ High speed parallel interface.

5. Power-Down Capability. When powered down the DAC

consumes less than 1 μA at 25°C.

6. Packaged in 20-lead DIP, SOIC and TSSOP packages.
