GENERAL DESCRIPTION

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

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

upon user demand.

The AD7390/AD7391 family of 10-bit and 12-bit voltage-

output digital-to-analog converters is designed to operate

from a single 3 V supply. Built using a CBCMOS process,

these monolithic DACs offer the user low cost, and ease-of-use

in single-supply 3 V 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.

Both parts are offered in the same pinout to allow users 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. The AD7391AR is

specified for the ꢀ40°C to ꢁ125°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

reference input voltage applied. The rail-to-rail REF_INto

DAC_OUTallows for a full-scale voltage set equal to the positive

supply V_DDor any value in between.

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

3-wire, SPI and microcontroller compatible inputs using data
