Azoteq Key Position Sensor Module
Azoteq is an IP-rich fabless semiconductor design house that pioneered multi-sensor technology on a single chip. It enables novel sensing applications for high-volume consumer goods. Azoteq sensor solutions are perfectly suited for integration in musical instruments.
1 Azoteq Full Motion Key Positional Sensor Module
- High resolution key motion (position vs time) data output on SPI
- Replaces traditional switch-based key sensors
- Polyphonic (poly) aftertouch via the same sensor
- Replaces the existing sensor module without modification to the key action
- Provides note on/off trigger velocities and continuous position using one inductive sensor
2 Output: Key Position and Derived Data
- Accurate position sampling, with clean, linear output
- High accuracy velocity, measured through the full keystroke
- Poly aftertouch available from the same sensor, no added cost
- Programmable threshold-triggered events
- Programmable lookup tables (LUTs) to transform position and derived data
- Many configurable filter stages are available to balance resolution with response rate
- Filter stages may be configured to derive instantaneous key velocities and accelerations (additional to "switch"-like trigger velocities)
3 Proven Technology
- Azoteq inductive sensors are based on a mature sensing platform developed for the gaming keyboard market
