DESCRIPTION The AA88348AP is a CMOS processed digital to analog converter (DAC) with 8-bit reso- lotion, low leakage current and low operating current. The AA88348AP 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. 10 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. 20 s settling time. AA88348AP is a single 5V power DAC. Analog DC output could be full voltage swing as the analog power i...
