Low Power — CM OS proprietary monolithic devices in
a unique circuit configuration yield the lowest power of
any 16-Bit converter available.
Tw o-Chip Construction — A n advanced monolithic
device, combined with our own resistor networks are all
that's needed in this converter. A utomatic wirebonding
makes the most consistently superior assembly available.
Input Storage Registers — Designed as two 8-Bit
segments, the input registers provide data storage when
latched, or " transparent" registers when unlatched.
Data conversion can now be performed continuously or
from stored data — " byte-sized" input segments provide
compatibility with most data bus lines.
Reliability — A proven performer, the DA C9331-16 is
packaged in a 24-pin ceramic double DIP for the utmost
in reliability. Combined with our proprietary monolithic
switches and automatic wirebonding, we've made the
DA C9331 -16 Series the most reliable industrial converter
to date. Reliability is further enhanced by batch-
processed. precision laser-trimmed resistor networks
fabricated in our own facility. Networks are functionally
trimmed and glass passivated to assure reliability under
adverse environmental conditions.
A dvanced designs, proven processes and continuous
monitoring during all production operations by our quali-
ty control organization are combined with rigorous A QL
screening to provide the most dependable, low cost D/A
converter possible.

DESCRIPTION
The DA C9331-16 Series are true 16-Bit D/A converters
manufactured with advanced proprietary monolithic
devices and proven performance packaging technique.
A single, unique monolithic chip contains switches,
storage registers and other electronics for high resolution
and low linearity error. A second, passive chip provides
all the needed resistors for these multiplying D/A 's. Input
storage registers are in two 8-Bit segments with indepen-
dent latching — compatible with microprocessor data bus
interfaces. It's a truly “ byte-sized” D/A input system. It
combines 2- and 4-quadrant multiplying capability. TTL/DTL
and CM OS compatibility; low power consumption (less
than 60 mW ) and operation from a single supply, the
DA C9331-16 Series offers exceptional performance/cost
ratio. Outstanding features include:
True 16-Bit Linearity —16-Bit (0.0008% ) linearity with
16-Bit resolution is now a reality. No other microcircuit
converter does better. 14- and 15-Bit linearity versions
available at lower cost.
