AA88347 datasheet


The AA88347 is a CMOS processed digital to analog converter (DAC) with 8-bit resolution, low leakage current and low operating current. The AA88347 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 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.


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

.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
