TJ 2 O Shutdown mode control signal input, sources a current proportional to the junction temperature. This pin should be left unconnected during normal operation. For more information, see the junction temperature measurement section of this document. LOUT + 3 O Left channel + output in BTL mode, + output in SE mode. L LINE IN 4 I Left channel line input, selected when HP/ LINE pin (16) is held low. LHP IN 5I Left channel headphone input, selected when HP/ LINE pin (16) is held high. LBYPASS 6 Connect to voltage divider for left channel internal mid-supply bias. LV DD 7 I Supply voltage input for left channel and for primary bias circuits. SHUTDOWN 8 I Shutdown mode control signal input, places entire IC in shutdown mode when held high, I DD= 0.5 µA. MUTE OUT 9 O Follows MUTE in pin (11), provides buffered output. LOUT - 10 O Left channel - output in BTL mode, high-impedance state in SE mode. MUTE IN 11 I Mute control signal input, hold low for normal operation, hold high to mute. SE/BTL 14 I Mode control signal input, hold low for BTL mode, hold high for SE mode. ROUT- 15 O Right channel - output in BTL mode, high impedance state in SE mode. HP/ LINE 16 I MUX control input, hold high to select headphone inputs (5,20), hold low to select line inputs (4,21). |
