DESCRIPTION

The SP9602 is a low power, dual 12–Bit Digital-to-Analog Converter. It features +4.5V output swings when using +5 volt supplies. The converter is double-buffered for easy microprocessor interface. Each 12–Bit DAC is independently addressable and both DACS may be simultaneously updated using a single transfer command. The output settling-time is specified at 30µs. The SP9602 is available in 28–pin SOIC and plastic DIP packages, specified over commercial temperature range.
