Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: Inputs AC-coupled to GND.
Note 3: A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined region of SCL’s
Note 4: C
Note 5: Input filters on SDA, SCL, and ADD suppress noise spikes of less than 50ns.
Note 6: Headphone mode testing performed with 32Ω resistive load connected to GND. Speaker mode testing performed with 8Ω
