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.
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
卤
15 V,
with references of +2.5 V to
卤
10 V respectively. Power dissipa-
tion when operating from
卤
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 鈥?5掳C to +125掳C tempera-
ture range.
