ML2330*
Selectable Dual 3V/3.3V/5V 8-Bit DACs
GENERAL DESCRIPTION
The ML2330 Selectable Dual 3V/3.3V/5V 8-bit DACs are
dual voltage output digital-to-analog converters which can
be independently programmed, or powered down to
conserve power. The devices are intended for use in
portable or low power 3V systems where space is critical.
Programming access to the DACs is provided over a high
speed (10Mb/s), 3-wire serial interface which is compatible
to the SPI™ and Microwire™ data formats. In addition to
independent programming of the DAC output voltages,
each device may be powered down, independent of the
other DAC, to conserve power. Each DAC draws 2mA
maximum quiescent current when operating, and typically
less than 1µA when powered down.
The device comes in an 8-pin SOIC package and in a
special Extended Commercial temperature range (–20°C
to 70°C) or Industrial temperture range (–40°C to 85°C).
