SDC-14600/05
TWO CHANNEL 14- AND 16-BIT
TRACKING S/D CONVERTERS
DESCRIPTION
The SDC-14600/05 Series are small
low cost dual synchro- or resolver-to-
digital converters. The SDC-14600
Series is fixed at 14 bits, the SDC-
14605 at 16 bits. The two channels
are independent tracking types but
share digital output pins and a com-
mon reference.
The velocity output (VEL) from the
SDC-14600/05 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 or excessive
converter error. Due to pin limitations
this option will exclude the velocity
output (contact factory).
SDC-14600/05 Series converters are
available with operating temperature
ranges of 0°C to +70°C and -55°C to
+125°C, and MIL-PRF-38534 pro-
cessing is available.
APPLICATIONS
With its low cost, small size, high
accuracy, and versatile performance,
the SDC-14600/05 Series converters
are ideal for use in modern high-per-
formance military and industrial posi-
tion control systems. Typical applica-
tions include radar antenna position-
ing, navigation and fire control sys-
tems, motor control, and robotics.
