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
鹵5
volt supplies. The converter is double-
buffered for easy microprocessor interface. Each 12-bit DAC is independently addressable and
all DAC
S
may be simultaneously updated using a single transfer command. The output settling-
time is specified at 4碌s. The
SP9504
is available in 28鈥損in SOIC and plastic DIP packages,
specified over commercial temperature range.
