AD2S80ABD

AD2S80ABD is Analog Devices' Resolver-to-Digital Converter (RDC). It demodulates a sine/cosine resolver and outputs a digital angular position via an SPI-compatible interface. It provides resolver offset/gain correction, fault diagnostics (e.g., amplitude/phase faults, reference loss), and status bits. It normally uses a single supply; the resolver excitation is supplied by the system or by the device per the variant. Outputs include an angle word plus status flags; data formats can be configured (single-turn, with some variants offering multi-turn behavior). The ABD suffix denotes a specific ordering variant (temperature range/packaging) within the AD2S80 family. Applications include servo drives, robotics, CNC machines, and other motor-control systems needing direct rotor-angle sensing from a resolver. How to use: connect the resolver’s sine/cosine to the RDC, power the device, and read angle data and status over SPI, handling any fault flags. For exact specs (pinout, timing, resolution, temperature range), consult the AD2S80ABD datasheet.

AD2S80ABD is a Resolver-to-Digital Converter (RDC) with Sin/Cos resolver inputs. Key features:
- Fully integrated RDC: demodulates sine and cosine resolver signals to digital angle data.
- SPI-compatible serial interface: four-wire, programmable frame formats and data rates.
- On-chip demodulation and filtering with automatic offset/gain calibration.
- Programmable output options: angle word format, data rate, and optional velocity estimation.
- Built-in diagnostics: fault detection for resolver open-circuit, short, and loss of signal.
- Industrial robustness: wide operating temperature range and suitable for rugged environments.
- Low-power, single-supply operation and compact packaging (ABD variant).
For exact electrical specs (voltage, resolution, update rate, and timing), refer to the AD2S80ABD datasheet.

- Pin count: 28 pins (28-pin package, e.g., SSOP/ DIP variants).
- Function: Resolver-to-digital converter (RDC). Drives the resolver excitation, demodulates the SIN/COS outputs from the resolver, and outputs a digital angle word via a serial interface (SPI-like) with pins such as CS, SCK, SDI, SDO. Requires separate analog/digital supplies and grounds (AVDD/AGND, DVDD/DGND) and provides related control/status pins (RESET, FAULT/READY, etc.). Exact pin names/pinout depend on the specific package variant; refer to the AD2S80ABD datasheet for the precise pinout.

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits and related products.
