■ General 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 8channels
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 is 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. 100μs settling time.
AA88347AP 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, AA88347AP is also available for electronic volume and instead of
potentiometers for adjustment due to its high stability on the capacitive load.
16 pins TSSOP package type are available for AA88347AP. Its operational temper- nature
range is specified over –20℃ to 85℃.
