iC-PT3348H Datasheet
6iC-C-HP. TPH..A.HSEDEnARcRoAdYeOrPbTlOueEN®CSODeEriReSspreliminary
FEATURES
o For code discs of 33 mm: iC-PT3320H, 3348H, 3325H
o Compact, high resolution incremental encoder ICs with up to
2500 CPR (native) and 10,000 CPR (interpolated)
o Monolithic HD Phased Array with excellent signal matching
o Moderate track pitch for relaxed assembly tolerances
o Low-noise signal amplifiers with high EMI tolerance
o Pin-selectable operating modes:
analog, comparated (x1), interpolated (x2, x4)
o Pin-selectable index gating:
ungated (1 T), B-gated (0.5 T), AB-gated (0.25 T)
o Complementary quadrature outputs: A, B, Z and NA, NB, NZ
o Commutation signal outputs: U, V, W
o Short-circuit-proof, current-limited, +/- 4 mA push-pull
o Analog signal output for ease of alignment and resolution
enhancement by external interpolation
o LED power control with 40 mA high-side driver
o Low power consumption from single 3.5 V to 5.5 V supply
o Operating temperature range of -40 °C to +120 °C
o Evaluation kits with LED and code disc available for sampling
Rev A3, Page 1/11
