-. ANALOG W DEVICES Digital- to-Synchro Converters I DSC1705/1706 I FEATURES Very Low Radius Vector Variation (Transformation Ratio) (:to.1%) High Accuracy (:t2 arc-mins at +25°C) 12- or 14.Bit Resolution No 5 Volt Power Supply Required MIL Spec/Hi Rei Versions Available Internal 1.3VA Amplifiers Internal Transformers (40PHz Option) No Trims or Adjustments Necessary APPLICATIONS Driving Control Transformers Driving Torque Receivers (with External Amplifiers) OServo Mechanisms Retransmission Systems BPositional Control SGENERAL DESCRIPTION OThe DSC1705 and DSC1706 are Digital-to-Synchro and Digital- to-Resolver converters capable of driving electromechanical Lloads of up to 1.3VA. EThey accept a 14- or 12-bit digital input representing angle Tand a reference voltage of either 60Hz or 400Hz, and produce Ea 3 wire or 4 wire output suitable for driving Synchros or MODELS AVAILABLE The two Digital to Synchro/Resolver converters described in this data sheet differ primarily in the areas of resolution and accuracy as follows: Model DSC1705XYZ is a 14-bit converter with an overall accuracy of :t4 arc-minutes. Model DSC 1706XYZ is a 12-bit converter with an overall Resolvers. accuracy of 18 arc-minutes. The 400Hz converters contain internal1.3V A amplifiers as well as output and reference transformers. The 60Hz versions contain internal 1.3VA amplifiers but require external output and reference transformers. If it is necessary to drive a load requiring more than 1.3VA, op...
