Overview
The AK2331 is an electronic volume into which 8 bit 4 channels of multiplication D/A converters are integrated on a single chip. The reference voltage of the D/A converter can be selected from one external path (VREF pin level) and internal three paths (VSS, AVDD, AVDD/2) for each channel and it can be used as a normal D/A converter or an electronic volume that attenuates signals from input pins VIN0 to VIN3. A buffer amplifier is incorporated as the subsequent stage of the D/A...
