●Product Details
●The AD7390/AD7391 family of 10- and 12-bit voltage-output digital-to-analog converters are designed to operate from a single +3 volt supply. Built using a CBCMOS process, these monolithic DACs offer the user low cost, and ease-of-use in single-supply +3 V volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V consuming less than 100 µA making this device ideal for battery operated applications.
●The full-scale voltage output is determined by the external reference input voltage applied. The rail-to-rail REFIN to DACOUT allows for a full-scale voltage set equal the positive supply VDD or any value in between.
●A doubled-buffered serial-data interface offers high-speed, three-wire, SPI and microcontroller compatible inputs using data in (SDI), clock (CLK) and chip select (CS/LD) pins. Additionally, a CLR input sets the output to zero scale at power on or upon user demand.
●Both parts are offered in the same pin out to allow the user to select the amount of resolution appropriate for their application without circuit card redesign.
●The AD7390/AD7391 are specified over the extended industrial (-40°C to +85°C) temperature range. AD7390/AD7391 are available in plastic DIP, and low profile 1.75 mm height SO-8 surface mount packages. For ultracompact applications the thin 1.1 mm TSSOP-8 package will be available.
