iC-PT 3310
preliminary
6-CH. PHASED ARRAY OPTO ENCODER (33-1000)
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°)
Rev A6, Page 1/9
APPLICATIONS
o Incremental encoder
o BLDC motor commutation
