Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: PSRR is specified with the amplifier inputs connected to GND through RIN and CIN.
Note 3: Refer to the SVDD section.
Note 4: A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined region of SCL’s falling
edge.
Note 5: CB = total capacitance of one of the bus lines in picofarads. Device tested with CB = 400pF. 1k
pullup resistors connected
from SDA/SCL to VDD.
Note 6: Input filters on SDA, SCL, and ADD suppress noise spikes of less than 50ns.
