GENERAL DESCRIPTION

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.

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.

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.

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.
