AD7390:  +3/+5 Volt Serial-Input Micropower 12-Bit DAC

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.
