... Pop Noise Suppression Since the TB2936HQ uses the AC-GND pin (pin 16) as the common input reference voltage pin for all amplifiers, the ratio of the input capacitance (C1) to the AC-to-GND capacitance (C6) should be 1:4. Also, if power is removed before C1 and C6 are completely charged, pop noise will be generated because of unbalanced DC currents ...
