DESCRIPTION
The RDC-19220/2S is a low-cost versatile state-of-the-art 16-bit
monolithic Resolver-to-Digital Converter. This single chip converter
offers programmable features such as resolution, bandwidth and
velocity output scaling.
Resolution programming allows selection of 10, 12, 14, or 16 bits,
with accuracies to 2.3 minutes. This feature combines the high track-
ing rate of a 10-bit converter with the precision and low-speed veloc-
ity resolution of a 16-bit converter in one package.
The internal Synthesized Reference section eliminates errors due to
quadrature voltage. Previously, a 6 degree phase shift caused prob-
lems for a 16-bit converter. The synthesized reference capability
ensures operation with a phase shift up to 45 degrees.
The velocity output (VEL) from the RDC-19220/2S, which can be
used to replace a tachometer, is a 4 V signal referenced to ground.
The full-scale value of VEL is set by the user with a single resistor.
The RDC-19220/2S converter is available with operating temperature
APPLICATIONS
The low cost, small size, high accuracy, and versatile performance of
the RDC-19220/2S converter makes it ideal for use in modern high
performance industrial control systems. Typical applications include
motor control, radar antenna positioning, machine tool control, robot-
ics, and process control.
