GENERAL DESCRIPTION
The AD7398/AD7399 family of quad, 12-bit/10-bit, voltage
output digital-to-analog converters (DACs) is designed to
operate from a single 3 V to 5 V supply or a dual ±5 V supply.
Built with the Analog Devices, Inc. robust CBCMOS process,
these monolithic DACs offer the user low cost with ease-of-use
in single or dual-supply systems.
The applied external reference, VREF, determines the full-scale
output voltage. Valid VREF values include VSS < VREF < VDD that
result in a wide selection of full-scale outputs. For multiplying
applications, ac inputs can be as large as ±5 VP.
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 simultaneous
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 asynchronous reset (RS) also
forces all registers to the zero code state. A programmable power-
shutdown feature reduces power dissipation on unused DACs.
Both parts are offered in the same pinout, enabling 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 are specified over the extended industrial
(40°C to +125°C) temperature range. Parts are available in
16-lead, wide body SOIC and ultracompact, thin, 1.1 mm
TSSOP packages.
