DESCRIPTION
The RDC-19220/2S is a low-cost, versatile, state-of-the-art 16-bit
monolithic Resolver-to-Digital (R/D) converter. This single chip converter offers programmable features such as resolution, bandwidth
and velocity output scaling.
• Programmable for LVDT Input
Resolution programming allows selection of 10, 12, 14, or 16 bits,
with accuracies to 1.3 minutes. This feature combines the high tracking rate of a 10-bit converter with the precision and low-speed velocity 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 problems 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
ranges of 0° to +70°C, -40° to +85°C, and -55° to +125°C.
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 motion control systems. Typical applications include
motor control, radar antenna positioning, machine tool control, robotics, and process control. Class K and MIL-PRF-38534 processing are
also available.
