[1] Operation above 16 V with a 2 Ω reactive load can trigger the amplifier protection. The amplifier switches off and will restart after 16 ms
resulting in an ‘audio hole’.
[2] V_STB depends on the current into the STB pin: minimum = (1429 × I_STB) + 5.4 V, maximum = (3143 × I_STB) + 5.6 V.
[3] The times are specified without a leakage current. For a leakage current of 10 µA on the SVR pin, the delta time is specified. If the
capacitor value on the SVR pin changes with ±30 %, the specified time will also change with ±30 %. The specified time includes an ESR
of the capacitor on the SVR pin of up to 15 Ω.
[4] Standard I²C-bus spec: maximum LOW level = 0.3 × V_DD, minimum HIGH-level = 0.7 × V_DD. To comply with 5 V and 3.3 V logic the
maximum LOW level is defined with V_DD = 5 V and the minimum HIGH-level with V_DD = 3.3 V.
[5] R_i is the total differential input resistance. f_−3dB cut-off frequency is defined as
2^----π^-----×^----R^----_i^-1--×^-----C^----_i^---⁄^---2^{- =} 2^----π^-----×^----4^---4^------k^---Ω^------×^--1--2^---3^---5^------n^---F^-----×^-----0^---.^--8^{- = 19 Hz assuming worst-case low input resistance and 20 % spread in Ci.}
