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 both DACS may be simultaneously updated using a single transfer command. The output settling-time is specified at 4µs. The SP9502 is available in 28–pin SOIC and DIP packages, specified over commercial temperature range.
