AA88347A Overview
The AA88347A is a CMOS processed digital to analog converter (DAC) with 8-bit resolution, low leakage and operating current. The AA88347A 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. Digital data (DI) input serially in a max.
