DESCRIPTION
The SD-14531 is a low-cost, high reliability, programmable synchro/
resolver-to-digital converter with pin programmable 14- or 16-bit res-
olution. Packaged in a 36-pin DDIP, the SD-14531 features Built-In-
Test (BIT) output.
The SD-14531 series accepts broadband inputs: 360 to 1 kHz, or 47
to 1 kHz. Other features include solid-state signal and reference iso-
lation and high common-mode rejection. The digital angle output from
the SD-14531 is a natural binary code, parallel positive logic and is
TTL/CMOS compatible. Synchronization to a computer is accom-
plished with the Converter Busy (CB) output and/or the Inhibit (INH)
input.
APPLICATIONS
Because of its high reliability, small size, and low power consumption,
the SD-14531 is ideal for military ground or avionics applications. All
models are available with MIL-PRF-38534 processing.
Designed with three-state output, the SD-14531 is especially well
suited for use with computer based systems. Among the many pos-
sible applications are radar and navigation systems, fire control sys-
tems, flight instrumentation and flight trainers or simulators.
