GENERAL DESCRIPTION
The AD7392/AD7393 family of 10- 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, 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. The voltage outputs are
capable of sourcing 5 mA.
A 12-bit wide data latch loads with a 45 ns write time allowing
interface to the fastest processors without wait states.
Additionally, an asynchronous
RS
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 applications
without circuit card changes.
The AD7392/AD7393 are specified for operation over the ex-
tended industrial (–40
°
C to +85
°
C) temperature range. The
AD7393AR is specified for the –40
°
C to +125
°
C automotive
temperature range. AD7392/AD7393s are available in plastic
DIP, and 20-lead SOIC packages. The AD7393ARU is avail-
able for ultracompact applications in a thin 1.1 mm height
TSSOP-20 package.
For serial data input, 8-lead packaged versions, see the AD7390
and AD7391 products.
