THE RD-19240 is a new low cost programmable 10,12 or 14 bit resolution ASIC tracking resolver-to-digital converter that is ideal for automotive applications. It is available from Allied Data Systems Pty Ltd .
This resolver-to-digital converter will be used in precision position measurement applications where low cost but ultra high reliability are required such as in ‘Drive by Wiring’ car steering applications.
This converter offers off-the-shelf solutions for today's high demand motion feedback applications. It features programmable 10, 12 and 14 bit resolution with accuracies to 8 arc minutes.
The resolver-to-digital converter may be configured for operation with a single +5Vdc power supply.
Programmable bandwidth for dual applications with a single resolver-to-digital converter and a velocity output used to replace tachometers may be scaled to the applications needs.
The velocity scale factor/tracking rate is programmed with a single resistor. The optional internal synthesised reference feature eliminates errors due to quadrature voltage and ensures operation with a rotor-to-stator phase shift of up to 45°.
Inputs may be configured for resolver, synchro, LVDT/RVDT and DC signals.
