GENERAL DESCRIPTION
The AD7390/AD7391 family of 10-bit & 12-bit voltage-output
digital-to-analog converters is designed to operate from a single
1
3 V supply. Built using a CBCMOS process, these monolithic
DACs offer the user low cost, and ease-of-use in single-supply
1
3 V systems. Operation is guaranteed over the supply voltage
range of
1
2.7 V to
1
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 ref-
erence 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,
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.
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
(
2
40
°
C to
1
85
°
C) temperature range. The AD7391AR is
specified for the
2
40
°
C to
1
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.
