6-CH. INCREMENTAL OPTO ENCODER ARRAY
Rev C1, Page 1/15
FEATURES
• Monolithic photodiode array with excellent signal matching
• Very compact size for small encoders
• Moderate track pitch for relaxed assembly tolerances
• Low noise signal amplifiers with high EMI tolerance
• Pin-selectable operating modes:
analog, comparated (x1), interpolated (x2, x4)
• Pin-selectable index gating:
ungated (1 T), B-gated (0.5 T), AB-gated (0.25 T)
• Complementary quadrature outputs: A, B, Z and NA, NB, NZ
• Commutation signal outputs: U, V, W
• Short-circuit-proof, current-limited, +/- 4 mA push-pull
• Analog signal output for ease of alignment and resolution
enhancement by external interpolation
• LED power control with 40 mA high-side driver
• Low power consumption from single 3.5 V to 5.5 V supply
• Operating temperature range of -40 °C to +120 °C
• Space saving optoQFN / optoBGA packages (RoHS compliant)
• Custom made code disc and reticle designs on request
APPLICATIONS
• Incremental encoder
• Brushless DC motor
commutation
• Industrial drives
