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 Ran...
