High Performance, 10-Bit to 16-Bit Resolver-to-Digital Converter based on AD2S1210

説明

• A complete high performance resolver-to-digital (RDC) circuit that accurately measures angular position and velocity in automotive, avionics, and critical industrial applications where high reliability is required over a wide temperature range. The circuit has an innovative resolver rotor driver circuit that has two modes of operation: high performance and low power. In the high performance state, the system operates on a single 12V supply and can supply 6.4 Vrms (18V p-p) to the resolver. In the low power state, the system operates on a single 6V supply and can supply 3.2 Vrms (9.2V p-p) to the resolver, with less than 100 mA of current consumption. Active filtering is provided in both the driver and receiver to minimize the effects of quantization noise
