DESCRIPTION
The RD-19240 is a low-cost, versatile, state-of-the-art 14-bit mono-
lithic Resolver-to-Digital (R/D) Converter. This single chip converter
offers programmable features such as resolution, bandwidth, velocity
output scaling, and encoder emulation.
Resolution programming allows selection of 10, 12, or 14 bits, with
accuracies to 8 minutes. This feature combines the high tracking rate
of a 10-bit converter with the precision and low-speed velocity reso-
lution of a 14-bit converter in one package. The parallel digital data
and the internal encoder emulation signals (A QUAD B) have inde-
pendent resolution control. Internal encoder emulation permits inhibit-
ing (freezing) the parallel digital data without interrupting the A and B
outputs.
The internal Synthesized Reference section eliminates errors due to
quadrature voltage. The synthesized reference capability ensures
operation with a phase shift up to 45 degrees. The velocity output
(VEL) from the RD-19240, which can be used to replace a tachome-
ter, is a 4 V signal referenced to ground. The full-scale value of VEL
is set by the user with a single resistor.
The converter provides the option of using a second set of filter com-
ponents which can be used in dual bandwidth or switch-on-the-fly
applications.
The RD-19240 converter is available with operating temperature
ranges of -40° to +85°C or -40° to +125°C.
