Encoding Characteristics
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances.
These Characteristics do not include codewheel/codestrip contribution. The Typical Values are averages over
the full rotation of the codewheel. For operation above 100 kHz, see frequency derating curves.
Frequency Derating Curves
Typical performance over extended operating range. These curves were derived using a 25 pF load with a 3.3
k pull-up resistor. Greater load capacitances will cause more error than shown in these graphs.
