GENERAL DESCRIPTION
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
μ
A
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 REF
IN
to
DAC
OUT
allows for a full-scale voltage set equal to the positive
supply V
DD
or any value in between.
A doubled-buffered serial-data interface offers high-speed,
3-wire, SPI and microcontroller compatible inputs using data
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.
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.
