FEATURES

• Synthesized Reference Option

The SD-14620 Series converters are

small, low-cost, two-channel hybrid

synchro- or resolver-to-digital con-

verters based on a single-chip mono-

lithic. The SD-14620XS option offers

synthesized reference circuitry to cor-

rect for phase shifts between the ref-

erence 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 track-

ing 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.

APPLICATIONS

With its low-cost, small size, high

accuracy and versatile performance,

the SD-14620 Series converters are

ideal for use in modern high-perfor-

mance military, commercial and space

position control systems. Typical appli-

cations include radar antenna posi-

tioning, motor control, robotics, navi-

gation and fire control systems.
