Part Number : AA88347
Function : CMOS processed digital to analog converter
Package : SOP 16 Pin Type
Manufacturers : Unspecified
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)
