It is closed at low level and opened at high level. This pin has a pull-down power inside When suspended, it is closed. High level Audio on Low level Audio o ff Hang in the air Audio o ff ALC anti-breaking sound enable The ALC pin is the anti-breaking tone enable control, it is closed when low level, and open when high level. This pin has a pull-up power inside Resistance, it is in the open state when suspended. High level Anti-breaking sound open Low level Anti-breaking sound o ff Hang in the air Anti-breaking sound open Peripheral parameter setting Gain setting: The ampli fi er gain is set through the external input resistance Ri, and the gain setting follows the following formula: Av=490k/(Ri+15k), Among them, 490k is the built-in feedback resistance, and 15k is the built-in input resistance. Customers can choose according to their own requirements for gain. If necessary, set the value of Ri fl exibly. 5W Anti-breaking Sound Mono Class D Audio Power Ampli fi er ANT8108 Product Manual V1.0 https://translate.googleusercontent.com/translate_f 4 of 5 8/4/21, 04:49 A3 A2 A D c h 0.25 L L1 A1 ANT8108 Product Manual V1.0 https://translate.googleusercontent.com/translate_f 5 of 5 8/4/21, 04:49
