Note 1: All voltages are referenced to ground.
Note 2: The value of V
Note 3: I
Note 4: I
Note 5: The DS1881 will not obstruct the SDA and SCL lines if V
Note 6: Guaranteed by design.
Note 7: Above Position 50, these are typical maximum. Guaranteed by characterization.
Note 8: Load is representative of the input of a low-noise audio amp.
Note 9: Timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I
Note 10: C
Note 11: If zero-crossing detection is enabled, the EEPROM write does not begin until the current zero-crossing detection is com-
