General Description
The AA88347L is a CMOS processed digital to analog converter (DAC) with 8-bit resolution, low leakage
current and low operating current. The AA88347L 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. Digital data(DI) input serially in a max. 2.5 MHz clock(CLK) rate. The latched
12-bit digital data are converted into an analog DC voltage in the range from VSS to VDD with 8-bit
resolution in one of the eight channels by the D/A converter in a max. 200μs settling time.

Features
.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 +3 V system power supply

Applications
.DVD,CD-R,CD-RW,DVC
.Digital camera
.Other industrial equipments
