AD2S1210

Variable Resolution, 10-Bit to 16-Bit R/D Converter with Reference Oscillator
Manufactured by:

Product Details

The AD2S1210 is a complete 10-bit 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.

The AD2S1210-EP supports defense and aerospace applications (AQEC)

Product Highlights

  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.
  2. 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.
  3. Input signal range. The sine and cosine inputs can accept differential input voltages of 3.15 V p-p ± 27%.
  4. Programmable excitation frequency. Excitation frequency is easily programmable to a number of standard frequencies between 2 kHz and 20 kHz.
  5. Triple format position data. Absolute 10-bit to 16-bit angular position data is accessed via either a 16-bit parallel port or a 4-wire serial interface. Incremental encoder emulation is in standard A-quad-B format with direction output available.
  6. Digital velocity output. 10-bit to 16-bit signed digital velocity accessed via either a 16-bit parallel port or a 4-wire serial interface.

Applications

  • DC and ac servo motor control
  • Encoder emulation
  • Electric power steering
  • Electric vehicles
  • Integrated starter generators/alternators
  • Automotive motion sensing and control

This product has great characteristics
The AD2S1210 is a 16-bit resolution tracking resolver-to-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers. we use it for rotor position detection for PMSM, when we adopt vector control to contorl PMSM in an EV,This product has great characteristics when using in our project, it can reach our requirement very well.
