The DAC8420 is available in 16-pin epoxy DIP, cerdip, and
wide-body SOL (small-outline surface mount) packages. Opera-
tion is specified with supplies ranging from +5 V-only to
±
15 V,
with references of +2.5 V to
±
10 V respectively. Power dissipa-
tion when operating from
±
15 V supplies is less than 255 mW
(max), and only 35 mW (max) with a +5 V supply.
For applications requiring product meeting MIL-STD-883,
contact your local sales office for the DAC8420/883 data sheet,
which specifies operation over the –55
°
C to +125
°
C tempera-
ture range.
GENERAL DESCRIPTION
The DAC8420 is a quad, 12-bit voltage-output DAC with serial
digital interface, in a 16-pin package. Utilizing BiCMOS tech-
nology, this monolithic device features unusually high circuit
density and low power consumption. The simple, easy-to-use
serial digital input and fully buffered analog voltage outputs
require no external components to achieve specified performance.
The three-wire serial digital input is easily interfaced to micro-
processors running at 10 MHz rates, with minimal additional
circuitry. Each DAC is addressed individually by a 16-bit serial
word consisting of a 12-bit data word and an address header.
The user-programmable reset control
CLR
forces all four DAC
outputs to either zero or midscale, asynchronously overriding
the current DAC register values. The output voltage range, de-
termined by the inputs VREFHI and VREFLO, is set by the
user for positive or negative unipolar or bipolar signal swings
within the supplies allowing considerable design flexibility.
