Note 1: All specifications are 100% tested at TA = +25°C. Temperature limits are guaranteed by design.
Note 2: VDD and PVDD must be connected together.
Note 3: Inputs AC-coupled to SGND.
Note 4: Both channels loaded and driven in phase.
Note 5: Headphone testing performed with a 32Ω resistive load connected to PGND. Mode transitions are controlled by SHDN. KCP
level is calculated as 20log[(peak voltage during mode transition, no input signal)/1VRMS]. Units are expressed in dBV.
Note 6: Guaranteed by design.
