SDC-14610/15 SERIES
THREE CHANNEL 14- AND 16-BIT
TRACKING S/D CONVERTERS
DESCRIPTION
The SDC-14610/15 Series are small low
cost triple synchro- or resolver-to-digital
converters. The SDC-14610 Series is
fixed at 14 bits, the SDC-14615 at 16
bits. The three channels are indepen-
dent tracking types but share digital out-
put pins and a common reference.
The velocity output (VEL) from the
SDC-14610/15 Series, which can be
used to replace a tachometer, is a 4 V
signal referenced to ground with a lin-
earity of 1% of output voltage.
A BIT output is optional and is a logic
line that indicates LOS (Loss Of
Signal) or excessive converter error.
Due to pin limitations this option will
exclude the velocity output.
SDC-14610/15 Ser ies conver t-
ers are available with operating
temperature ranges of 0°C to
+70°C and -55°C to +125°C, and
MIL-PRF-38534
processing
is
available.
APPLICATIONS
With its low cost, small size, high
accuracy,
and
versatile
perfor-
mance, the SDC-14610/15 Series
converters are ideal for use in mod-
ern high-performance military and
industrial position control systems.
Typical applications include radar
antenna positioning, navigation and
fire control systems, motor control,
and robotics.
