RDC19222-302

Product Summary

The RDC19222-302 is a 16 bit monolithic tracking resolver to digital converter. The converter offers low cost off-the-shelf solutions for todays motion feedback applications. Class K and Mil-PRF-38534 processing options are also available. This single chip converter RDC19222-302 features programmable resolution of 10, 12, 14 or 16 bits with accuracies to 1.3 min. This converter RDC19222-302 can be configured for operation with a single +5VDC power supply. Programmable bandwidth and a velocity output used to replace tachometers can be scaled to your application needs. The velocity scale factor / tracking rate is programmed with a single resistor. The optional internal synthesized reference feature will eliminate errors due to quadrature voltage and ensure operation with a rotor-to-stator phase shift of up to 45 degrees. The RDC19222-302 offers versatile performance at low cost for use in industrial control systems. Standard selections for Class K and MIL-PRF processing reduce lead time costs and no NRE or lot charges are necessary.
