GENERAL DESCRIPTION
The AD7392/AD7393 comprise a set of pin-compatible
10-/12-bit voltage output, digital-to-analog converters. The
parts are designed to operate from a single 3 V supply. Built
using a CBCMOS process, these monolithic DACs offer 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 ref-
erence input voltage applied. The rail-to-rail REFIN to DACOUT
allows a full-scale voltage equal to the positive supply VDD or
any value in between. The voltage outputs are capable of sourc-
ing 5 mA.
A data latch load of 12 bits with a 45 ns write time eliminates
wait states when interfacing to the fastest processors. Addition-
ally, an asynchronous RS input sets the output to a zero scale at
power-on or upon user demand.
Both parts are offered with similar pinouts, which allows users
to select the amount of resolution appropriate for their applica-
tions without changing the circuit card.
The AD7392/AD7393 are specified for operation over the
extended industrial temperature range of 40°C to +85°C.
The AD7393AR is specified for the automotive temperature
range of 40°C to +125°C. The AD7392/AD7393 are available
in 20-lead PDIP and 20-lead SOIC packages.
For serial data input, 8-lead packaged versions, see the AD7390
and AD7391.
