SD-14620 SERIES
TWO-CHANNEL SYNCHRO/RESOLVER-
TO-DIGITAL (S/R-D) CONVERTERS
DESCRIPTION
The SD-14620 Series converters are small, low-cost, two-channel
hybrid Synchro- or Resolver-to-Digital converters based on a single-
chip monolithic. The SD-14620X“S” option offers synthesized refer-
ence circuitry to correct for phase shifts between the reference and
signal inputs. The two channels are independent but share the digital
output and +5 VDC power pins. The package is 54-pin ceramic, yet is
the size of a 28-pin DDIP.
Resolution programming allows selection of 10-, 12-, 14- or 16-bit
modes. This feature allows selection of either low-resolution for fast
tracking or higher resolution for higher accuracy.
The velocity outputs (VEL A, VEL B) of the SD-14620 Series, which can
be used to replace a tachometer, are ±4 V signals referenced to analog
ground.The SD-14620 Series also offers Built-In-Test outputs for each
channel (BIT-A, BIT-B). The converters are available with operating
temperature ranges of 0°C to +70°C, -40°C to +85°C and -55°C to
+125°C. MIL-PRF-38534 processing is available.
