ML2330

July 2000 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). *Some Packages Are End Of Life Or Obsolete FEATURES s s s s s s 3V ±10%, 3.3 ±10% or 5V ±10% operation Low supply current (3.5mA max) Individual and full power down (down to 1µA) 10Mb/s three-wire serial interface, compatible to SPI and Microwire 8-pin SOIC package Available in Extended Commercial temperature range (–20°C to 70°C) and Industrial temperture range (–40°C to 85°C) Guaranteed monotonicity s BLOCK DIAGRAM 8 VCC R E G SCLK DAC A OUT A 7 20kΩ 2 1 DIN CONTROL AND TIMING VREF POWER DOWN 3 CS 4 DOUT R E G OUT B DAC B 20kΩ 6 GND 5 1 ML2330 PIN C...
