DESCRIPTION
The DA C9377-16 is a complete, voltage output 16-bit
D/A converter with true 16-bit linearity. Complete
with storage registers, internal reference and output
amplifier, the DA C9377-16 provides the user with
exceptional performance and self-contained
operation. The input storage register is composed of
16 parallel latches — a system compatible with 16-bit
data bus interfaces. A single proprietary monolithic
chip contains switches, storage registers and other
electronics for high resolution and low linearity error.
TTL and CM OS compatibility combined with low
power dissipation in a ceramic 24-pin DIP makes the
DA C9377-16 unsurpassed in a high resolution data
conversion device.
True 16-Bit Linearity — 16-bit (±0.0008% ) linearity in
a 24-pin DIP is unequaled. No other microcircuit
converter does better. A dditional versions with 15-
and 14-bit linearity are also available.
Low Pow er — CM OS proprietary monolithic devices
in a unique circuit configuration yield the lowest
power dissipation (450 mW typ.) of any complete 16-
bit converter available.
Complete — No external components are required
for 16-bit conversion.
Input Storage Registers — Designed in one 16-bit
segment, the input storage register provides data
storage when latched, but is “ transparent” when
unlatched. The latch control is level triggered for
either static or dynamic operation.
Reliability — A proven performer, the DA C9377-16 is
packaged in a 24-pin ceramic DIP for the utmost in
reliability. Combined with our proprietary monolithic
device and automatic wirebonding, we‘ve made the
DA C9377-16 the most reliable device to date.
Reliability is further enhanced by batch-processed,
precision laser-trimmed resistor networks fabricated
in our own facility.
A dvanced designs, proven processes and continuous
monitoring during all production operations by our
quality control organization are combined with
rigorous A QL screening to provide the most
dependable, low cost D/A converter possible.
