TIMING CHARACTERISTICS
(VDD = SHDN = 5V, PGND = SGND = 0V, C1 = C2 = 1F, CPREG = CNREG = 1F, BM_ = 0V, RIN = 10kΩ, RF = 10kΩ, maximum vol-
ume (overall gain = 0dB), BassMax disabled. Load connected between OUT_ and PGND where specified. TA = TMIN to TMAX, unless
otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 3)
Note 1: All specifications are 100% tested at TA = +25°C. Temperature limits are guaranteed by design.
Note 2: Inputs AC-coupled to SGND.
Note 3: Guaranteed by design.
Note 4: 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.
