Low Cost, Complete 12-Bit Resolver-to-Digital Converter
Description:
The AD2S90 is a complete 12-bit resolution tracking resolver-to-digital converter. No external components are required tooperate the device.The converter accepts 2 V rms ± 10% input signals in the range3 kHz–20 kHz on the SIN, COS and REF inputs. A Type IIservo loop is employed to track the inputs and convert the inputSIN and COS information into a digital representation of theinput angle. The bandwidth of the converter is set internally at1 kHz within the tolerances of the device. The guaranteed maxi-mum tracking rate is 500 rps.Angular position output information is available in two forms,absolute serial binary and incremental A quad B.The absolute serial binary output is 12-bit (1 in 4096). The dataoutput pin is high impedance when Chip Select CS is logic HI.This allows the connection of multiple converters onto a com-mon bus. Absolute angular information in serial pure binaryform is accessed by CS followed by the application of an exter-nal clock (SCLK) with a maximum rate of 2 MHz.The encoder emulation outputs A, B and NM continuouslyproduce signals equivalent to a 1024 line encoder. When de-coded this corresponds to 12 bits of resolution. Three commonnorth marker pulsewidths are selected via a single pin (NMC).An analog velocity output signal provides a representation ofvelocity from a rotating resolver shaft traveling in either a clock-wise or counterclockwise direction.The AD2S90 operates on ±5 V dc ± 5% power supplies and isfabricated on Analog Devices’ Linear Compatible CMOS pro-cess (LC2MOS). LC2MOS is a mixed technology process thatcombines precision bipolar circuits with low power CMOS logiccircuits.
