Digitally Controlled Calibration

A doubled-buffered serial-data interface offers high speed,

three-wire, SPI and microcontroller compatible inputs using

data in (SDI), clock (CLK) and load strobe (LD) pins. Addi-

tionally, a CLR input sets the output to zero scale at power on

or upon user demand.

GENERAL DESCRIPTION

The AD7390/AD7391 family of 10-bit & 12-bit voltage-output

digital-to-analog converters is designed to operate from a single

ϩ3 V supply. Built using a CBCMOS process, these monolithic

DACs offer the user low cost, and ease-of-use in single-supply

ϩ3 V systems. Operation is guaranteed over the supply voltage

range of ϩ2.7 V to ϩ5.5 V consuming less than 100 µA making

this device ideal for battery operated applications.

Both parts are offered in the same pinout to allow users to select

the amount of resolution appropriate for their application with-

out circuit card redesign.

The AD7390/AD7391 are specified over the extended industrial

(Ϫ40°C to ϩ85°C) temperature range. The AD7391AR is

specified for the Ϫ40°C to ϩ125°C automotive temperature

range. The AD7390/AD7391s are available in plastic DIP, and

low profile 1.75 mm height SO-8 surface mount packages. The

AD7391ARU is available for ultracompact applications in a thin

1.1 mm TSSOP-8 package.

The full-scale voltage output is determined by the external ref-

erence input voltage applied. The rail-to-rail REF_INto DAC_OUT

allows for a full-scale voltage set equal to the positive supply

V_DDor any value in between.
