AS5510 − Electrical Characteristics

CMOS I²C: SDA, SCL

Operating conditions: Tamb = -30°C to 85°C, VDD = 2.5V to 3.6V

(3V operation) unless otherwise noted.

Electrical Characteristics I²C

Note(s) and/or Footnote(s):

1. In Fast-mode Plus, fall time is specified the same for both output stage and bus timing. If series resistors are used this has to be

considered for bus timing.

2. Input filters on the SDA and SCL inputs suppress noise spikes of less than 50 ns.

3. I/O pins of Fast-mode and Fast-mode plus devices must not obstruct the SDA and SCL lines if VDD is switched OFF.

4. Special purpose devices such as multiplexers and switches may exceed this capacitance due to the fact that they connect multiple

paths together.
