The AD22057 is a single-supply difference amplifier for the amplification and low-pass filtering of small differential voltages from sources having a large common-mode voltage.Supply voltages from +3 V to +36 V can be used. The input common-mode range extends from below ground to 24 V using a +5 V supply with excellent rejection of this common-mode voltage.This range is achieved by the use of a special resitive attenuator at the input, laser trimmed to a very high differential balance. Low initial offset voltage and offset voltage drift are specified, and long-term stability of gain and offset voltage is also provided.Provisions are included for optional low-pass filtering and gain adjustment.

The AD2S90 is a complete 12-bit resolution tracking resolver-to- 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. The maximum tracking rate is 375 rps at 12-bit resolution.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 resolution.
