AEAS-7500
Overview
The encoder IC consists of 13 signal photo diode channels and 1 monitor photo diode channel and is used for the optical reading of rotary or linear code carriers (i.e. discs or scales). The photodiodes are accompanied with precision amplifiers plus additional circuitry.
- The gain and offset conditioning value of the sine and cosine signals are preloaded on-chip by factory. This will minimize mechanical sensor misalignment error. Features
- Two Sine/Cosine true differential outputs with 1024 periods for unit alignment
- Integrated highly collimated illumination system
- 11 digital tracks plus 2 sin/cos tracks generate precise 16 bit Gray code
- Ultra fast, 1µs cycle for serial data output word equals 16MHz
- The 12 bits MSB is functionable up to 12000 RPM, 16 bit up to 1000RPM
- MSB can be inverted for changing the counting direction
- Monitor track for tracking the light lev
