DESCRIPTION
The RD-19240 is a low-cost, versatile, state-of-the-art 14-bit monolithic
Resolver-to-Digital (R/D) Converter. This single chip converter offers pro-
grammable features such as resolution, bandwidth, velocity output scal-
ing, and encoder emulation.
Resolution programming allows selection of 10, 12, or 14 bits, with accu-
racies to 8 minutes. This feature combines the high tracking rate of a 10-
bit converter with the precision and low-speed velocity resolution of a 14-
bit converter in one package. The parallel digital data and the internal
encoder emulation signals (A QUAD B) have independent resolution con-
trol. Internal encoder emulation permits inhibiting (freezing) the parallel
digital data without interrupting the A and B outputs.
The internal Synthesized Reference section eliminates errors due to quadra-
ture voltage, ensuring operation with a phase shift up to 45°. The velocity out-
put is a 4 V signal referenced to ground, and can be used to replace a tachome-
ter. The full-scale velocity value is set by the user with a single resistor.
The converter provides the option of using a second set of filter compo-
nents which can be used in dual bandwidth or switch-on-the-fly applica-
tions. The RD-19240 converter is available with operating temperature
ranges of -40° to +85°C or -55° to +125°C.
APPLICATIONS
The low cost, small size, high accuracy, and versatile performance of the
RD-19240 converter make it ideal for use in modern high performance
industrial and automotive control systems. It is especially suited for users
who wish to use a resolver input in their encoder-based system. Typical
applications include motor control, factory automation, hybrid electric
vehicles, and steering.
