iC-PT 3310

6-CH. PHASED ARRAY OPTO ENCODER (33-1000)

Rev A6, Page 1/9

FEATURES

o Monolithic photodiode array with excellent signal matching

o Very compact size for small encoders

o Moderate track pitch for relaxed assembly tolerances

o Low noise signal amplifiers with high EMI tolerance

o Single-pin programming of 3 operating modes:

analog, digital, and x2 interpolation

o A-AND-B gated Z index signal

o Complementary outputs: A, B, Z and NA, NB, NZ

o U, V, W commutation signals (digital/analog)

o All outputs +/- 4 mA push-pull, current-limited and

short-circuit-proof

o LED power control with 40 mA high-side driver

o Single 3.5 V to 5.5 V operation, low power consumption

o Operating temperature range of -40 to +85 °C

(optional -40 to +120 °C)

o Suitable code disc: PT2S 33-1000 (glass)

OD ∅33.2 mm, ID ∅13.0 mm, optical radius 14.5 mm,

1000 ppr and 3 ppr commutation (120°)

APPLICATIONS

o Incremental encoder

o BLDC motor commutation
