GENERAL DESCRIPTION
The AD7398/AD7399 family of quad, 12-bit/10-bit, voltage-
output digital-to-analog converters is designed to operate from a
single 3 V to 5 V or a dual
±
5 V supply. Built with Analog’s robust
CBCMOS process, this monolithic DAC offers the user low
cost, and ease-of-use in single or dual-supply systems.
The applied external reference V
REF
determines the full-scale
output voltage. Valid V
REF
values include V
SS
< V
REF
< V
DD
that
result in a wide selection of full-scale outputs. For multiplying
applications ac inputs can be as large as
±
5 V
P
.
A doubled-buffered serial-data interface offers high-speed,
3-wire, SPI and microcontroller-compatible inputs using serial-
data-in (SDI), clock (CLK), and a chip-select (
CS
). A common
level-sensitive load-DAC strobe (
LDAC
) input allows simulta-
neous update of all DAC outputs from previously loaded Input
Registers. Additionally, an internal power ON reset forces the
output voltage to zero at system turn ON. An external asynchro-
nous reset (
RS
) also forces all registers to the zero code state. A
programmable power-shutdown feature reduces power dissipa-
tion on unused DACs.
Both parts are offered in the same pinout to enable users to
select the appropriate resolution for their application without
redesigning the layout. For 8-bit resolution applications see the
pin compatible AD7304 product.
The AD7398/AD7399 is specified over the extended industrial
(–40
°
C to +125
°
C) temperature range. Parts are available in
wide body SOIC-16 and ultracompact thin 1.1 mm TSSOP-
16 packages.
