PRELIMINARY

8-BIT DAC

■ DESCRIPTION

The AA88349 is a CMOS processed digital to analog converter (DAC) with 8-bit reso-

lotion, low leakage and operating current. The AA88349 has 3 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. 2.5MHz clock (CLK) rate. The latched 12-bit digital data is

converted into an analog DC voltage in the range from GND to VCC with 8-bit resolution

in one of the 3 channels by the D/A converter in a max. 100μs settling time. AA88349 is a

single 5V power DAC. Analog DC output could be full voltage swing as the analog power

is equal to the system power. In addition to normal D/A converter applications, AA88349 is

also available for electronic volume and instead of potentio- meters for adjustment due to

its high stability on the capacitive load. 8 pins TSSOP package type are available for

AA88349. Its operational temper- nature range is specified over –20℃ to 85℃.

■ FEATURES

• 12 bits serial data input (3 wire serial data transfer method, DI, CLK, LD)

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

• 3 channels with 8-bit resolution monotonic D/A converter

• 3 channels buffer operational amplifiers operating in the full voltage range from VCC to

GND

• Max. 2.5 MHz serial digital data input

• Serial I/O for cascade application

• Max. 1.0 mA output drive/sink current

• Single +5 V system power supply

■ APPLICATION

DVD, CD-R, CD-RW, DVC, digital camera, and other industrial equipments
