AD2S1210 is a 10-bit to 16-bit resolution rotation-to-digital converter that integrates an on-chip programmable sine wave oscillator to provide sine wave excitation to the rotary.
The converter's sine and cosine inputs allow input of signals in the 2 kHz to 20 kHz range at 3.15 V p-p ± 27%. Type II servo loops are used to track input signals and convert information from the sine and cosine inputs into digital quantities corresponding to the input angle and speed. The maximum tracking rate is 3125 RPS.
AD2S1210-EP supports defense and aerospace applications (AQEC).
Product Focus
1. Ratio tracking conversion. Type II tracking loops are capable of continuously outputting position data with no conversion delay. It also suppresses noise, as well as harmonic distortion tolerance for reference and input signals.
2. System fault detection. Fault detection circuitry can detect rotary signal loss, out-of-range input signals, input signal mismatches, or loss of position tracking. Each fault detection threshold can be individually programmed by the user to optimize for specific applications.
3. Input signal range. The sine and cosine inputs support a differential input voltage of 3.15 V p-p ± 27%.
4. Programmable excitation frequency. The excitation frequency can be easily set to multiple standard frequencies in the range of 2 kHz to 20 kHz.
5. 3x format position data. 10-bit to 16-bit absolute angular position data can be accessed via a 16-bit parallel port or a 4-wire serial interface. Incremental encoder emulation is in standard A-quad-B format with directional output.
6. Digital speed output. 10-bit to 16-bit symbolized digital volume speeds can be accessed via a 16-bit parallel port or a 4-wire serial interface
