MB88344 Overview
MB88344/MB88344B are 8-bit 36 channels D/A converters which have two reference voltages to use 36 channels as 12 channels and 24 channels independently. Each output channels has an operational amplifier output buffer and so large current drive is possible. In the MB88344B, 6 Channels of DAC output (AO31-AO36) have four data registers each and so, the analog output can be changed by the address input from A0 and A1...
