1. Ratiometric tracking conversion. The Type II tracking loop provides continuous output position data without conversion delay. It also provides noise immunity and tolerance of harmonic distortion on the reference and input signals. System fault detection. A fault detection circuit can sense loss of resolver signals, out-of-range input signals, input signal mismatch, or loss of position tracking. The fault detection threshold levels can be individually programmed by the user for optimization within a particular application. Input signal range. The sine and cosine inputs can accept differential input voltages 3.15 V p-p 27%. Programmable excitation frequency. Excitation frequency is easily programmable to a number of standard frequencies between 2 kHz and 20 kHz. Triple format position data. Absolute to 16-bit angular position data is accessed via either a 16-bit parallel port a 4-wire serial interface. Incremental encoder emulation is in standard A-quad-B format with direction output available. Digital velocity output. to 16-bit signed digital velocity accessed via either a 16-bit parallel port a 4-wire serial interface.

The is a complete to 16-bit resolution tracking resolver-to-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. The converter accepts 3.15 V p-p 27% input signals, in the range of 2 kHz to 20 kHz on the sine and cosine inputs. A Type II servo loop is employed to track the inputs and convert the input sine and cosine information into a digital representation of the input angle and velocity. The maximum tracking rate is 3125 rps. Full details about this enhanced product, including theory of operation, registers details, and applications information, are available in the AD2S1210 data sheet, which should be concluded in conjunction with this data sheet.
