GENERAL DESCRIPTION
The DAC8420 is a quad, 12-bit voltage-output DAC with serial
digital interface in a 16-lead 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 a specified per-
formance.
The 3-wire serial digital input is easily interfaced to micro-
processors running at 10 MHz 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 scale or midscale,

asynchronously overriding the current DAC register values. The
output voltage range, determined 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-lead PDIP, SOIC, and CERDIP
packages. Operation is specified with supplies ranging from
+5 V only to ±15 V, with references of +2.5 V to ±10 V, respec-
tively. Power dissipation when operating from ±15 V supplies is
less than 255 mW (maximum) and only 35 mW (maximum)
with a +5 V supply.
