TVOET3309N Transmissive Encoder Chip
The TVOET3309N series is another phase array cursor encoder chip for absolute encoders, featuring a similar design with multiple differential photodiodes (PD) arranged in a phase array. It produces high precision 3-channel (N channel, S channel, M channel) sinusoidal outputs, supporting interpolation up to 22 bits. The special PD design aids in achieving higher amplitude outputs under low illumination, further lowering LED current and extending the device’s lifespan.
