This feature combines the high trackingrate of a 10-bit converter with the precision and low-speed velocityresolution of a 16-bit converter in one package.The velocity output (VEL) from the RDC-19220 Series, which can beused to replace a tachometer, is a 4 V signal (3.5 V with the +5 V onlyoption) referenced to ground with a linearity of 0.75% of output voltage.The full scale value of VEL is set by the user with a single resistor.RDC-19220 Series converters are available with operating tempera-ture ranges of 0° to +70°C, -40° to +85°C and -55° to +125°C. Militaryprocessing is available (consult factory).APPLICATIONSWith its low cost, small size, high accuracy and versatile performance,the RDC-19220 Series converter is ideal for use in modern high-per-formance industrial and military control systems. Typical applicationsinclude motor control, radar antenna positioning, machine tool con-trol, robotics, and process control. MIL-PRF-38534 processing isavailable for military applications.© 1999 Data Device CorporationRDC-19220 SERIES16-BIT MONOLITHIC TRACKING RESOLVER(LVDT)-TO-DIGITAL CONVERTERS FEATURES• +5 Volt Only Option• Only Five External PassiveComponents• Programmable:- Resolution: 10-, 12-, 14-, or 16-Bit- Bandwidth: to 1200 Hz- Tracking: to 2300 RPS• Differential Resolver and LVDTInput Modes• Velocity Output EliminatesTachometer• Built-In-Test (BIT) Output• Small Size: 40-Pin DDIP or44-Pin J-Lead Package• -55° to +125°C OperatingTemperature Available• Programmable for LVDT input |
