SD-14595/96/97
SYNCHRO/RESOLVER-TO-DIGITAL
CONVERTERS
DESCRIPTION
The SD-14595 is a low-cost, high
reliability, synchro- or resolver-to-dig-
ital converter with 14-bit-only, 16-bit-
only or pin programmable 14-bit or
16-bit resolution. Packaged in a 36-
pin DDIP, the SD-14595/96/97 series
feature Built-In-Test (BIT) output.
The SD-14595/96/97 series accepts
broadband inputs: 360 to 1 kHz. Other
features are solid-state signal and ref-
erence isolation and high common
mode rejection. In addition, the SD-
14596 and SD-14597 are pin-for-pin
replacements for the Natel 1044 and
1046, respectively.
The digital angle output from the
SD-14595/96/97 is a natural binary
code, parallel positive logic and is
TTL/CMOS compatible. The SD-
14595/96/97 accomplishes synchro-
nization to a computer with the
Converter Busy (CB) output and/or the
Inhibit (INH) input.
FEATURES
Single +5 V Power Supply
Accuracy to 1.3 Arc Minutes
Pin Programmable 14 Bit/16 Bit,
14 Bit Only or 16 Bit Only
APPLICATIONS
Because of its high reliability, small
size, and low power consumption, the
SD-14595/96/97 is ideal for military
ground or avionics applications. All
models are available with MIL-PRF-
38534 processing.
Designed with three-state output, the
SD-14595/96/97 is especially well-
suited for use with computer based
systems. Among the many possible
applications are radar and navigation
systems, fire control systems, flight
instrumentation, and flight trainers or
simulators.
