DESCRIPTION

The SP9604 is a very 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 double-buffered for easy microprocessor interface. Each 12-bit DAC is independently

addressable and all DACs may be simultaneously updated using a single transfer command. The

output settling-time is specified at 30µs. The SP9604 is available in 28–pin SOIC and plastic DIP

packages, specified over commercial temperature range.
