DESCRIPTION The SP9504 is a low power replacement for the popular SP9345, Quad 12-Bit Digital-to-Analog Converter. It features +4.5V output swings when using ±5 volt supplies. The converter is doublebuffered for easy microprocessor interface. Each 12-bit DAC is independently addressable and all DACS may be simultaneously updated using a single transfer command.
