    AD2S90 - Analog Devices - Low Cost, Complete 12-Bit Resolver-to-Digital Converter

    Quick Detail:

    Low Cost, Complete 12-Bit Resolver-to-Digital Converter


    The AD2S90 is a complete 12-bit resolution tracking resolverto-digital converter. No external components are required to operate the device.

    The converter accepts 2 V rms ± 10% input signals in the range

    3 kHz–20 kHz on the SIN, COS and REF inputs. A Type II servo loop is employed to track the inputs and convert the input

    SIN and COS information into a digital representation of the input angle. The bandwidth of the converter is set internally at 1 kHz within the tolerances of the device. The guaranteed maximum 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 data output pin is high impedance when Chip Select CS is logic HI.

    This allows the connection of multiple converters onto a common bus. Absolute angular information in serial pure binary form is accessed by CS followed by the application of an external clock (SCLK) with a maximum rate of 2 MHz.

    The encoder emulation outputs A, B and NM continuously produce signals equivalent to a 1024 line encoder. When decoded this corresponds to 12 bits of resolution. Three common north marker pulsewidths are selected via a single pin (NMC).

    An analog velocity output signal provides a representation of velocity from a rotating resolver shaft traveling in either a clockwise or counterclockwise direction.

    The AD2S90 operates on ±5 V dc ± 5% power supplies and is fabricated on Analog Devices’ Linear Compatible CMOS process (LC2 MOS). LC2

    MOS is a mixed technology process that combines precision bipolar circuits with low power CMOS logic circuits.
