DESCRIPTION

The AA88347AP is a CMOS processed digital to analog converter (DAC) with 8-bit reso- lotion, low leakage current and low operating current. The AA88347AP has 8 channels with build in operational amplifier output buffers which could operate in the full-swing voltage range from VCC to GND and enhance the Drive/Sink ability up to max. 1mA.

FEATURE

● 12 bits serial data input(3 wire serial data

transfer method, DI, CLK, LD)

● R-2R resistor ladder used for D/A conversion

● 8 channels with 8-bit resolution monotonic D/A

converted

● 8 channel buffer operational amplifiers operating

in the full voltage range from VCC to GND only

if VDD=VCC and VSS=GND

● Max. 2.5 MHz serial digital data input

● Serial I/O for cascade application

● Max. 1.0 mA output drive/sink current

● Two separate power supply/ground lines for

system and analog power supply

● Single +5 V system power supply
