DESCRIPTION
The RD-19230 is a small and versatile, low cost, state-of-the-art 16-
bit monolithic Resolver-to-Digital Converter. This single chip convert-
er offers programmable features such as resolution, bandwidth,
velocity output scaling and encoder emulation.
Resolution programming allows selection of 10, 12, 14, or 16 bit, with
accuracies to 2.3 min. The parallel digital data and the internal
encoder emulation signals (A QUAD B) have independent resolution
control. Internal encoder emulation will permit inhibiting (freezing) the
parallel digital data without interrupting the A and B outputs.
The internal Synthesized Reference section eliminates errors due to
quadrature voltage and ensures operation with a rotor-to-stator phase
shift of up to 45 degrees. The velocity output (VEL) can be used in
place of a tachometer. It has a range of 鹵4 V relative to analog
ground. The velocity scale factor/tracking rate is programmed with a
single resistor. This converter provides the option of using a second
set of filter components which can be used in dual bandwidth or
switch on the fly applications.

APPLICATIONS
With its low cost, small size, high accuracy, and versatile perfor-
mance, the RD-19230 converter is ideal for use in modern high per-
formance industrial control systems. It is ideal for users who wish to
use a resolver input in their encoder based system. Typical applica-
tions include motor control, machine tool control, robotics, and
process control.
