Connected to thermal pad. I I I O O I Left channel headphone input, selected when SE/BTL is held high. mon left input for fully differential input. AC ground for single-ended inputs. Left channel line input, selected when SE/BTL is held low. Left channel positive output in BTL mode and positive output in SE mode. Left channel negative output in BTL mode and high-impedance in SE mode. The input for PC Beep mode. PC-BEEP is enabled when a > 1-V (peak-to-peak) square wave is input to PC-BEEP or PCB ENABLE is high. HP/LINE is the input MUX control input. When the HP/LINE terminal is held high, the headphone inputs (LHPIN or RHPIN [6, 20]) are active. When the HP/LINE terminal is held low, the...
