DESCRIPTION
The SD-14620 Series converters are small, low-cost, two-channel hybrid Synchro- or Resolver-to-Digital converters based on a singlechip monolithic. The SD-14620X“S” option offers synthesized reference 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.
- -55°C to +125°C Operating Temperature Range
- MIL-PRF-38534 Processing Available
APPLICATIONS
With its low-cost, small size, high accuracy and versatile performance, the SD-14620 Series converters are ideal for use in modern high-performance military, mercial and position control systems. Typical applications include radar antenna...
