DESCRIPTION
Power ground; directly connected to thermal pad.
Tap to left channel internal mid-supply voltage divider bias
No connection
Tap to right channel internal mid-supply voltage divider bias
I Left channel line input; selected when HP/LINE is held low
I Left channel headphone input; selected when HP/LINE is held high
I Left channel power supply and for primary bias circuits
I Places entire IC in shutdown mode when held high, I_DD = 5µA
I Follows MUTE IN, provides buffered output
I
Mute all amplifiers input; high active to mute amplify, low active to normal
operation
SE & BTL mode selection; active high for SE mode, active low for BTL
I _mode
I
MUX control input, active high to select headphone input, active low to
select line input
I Right channel power supply
I Right channel headphone input, selected when HP/LINE is held high
I Right channel line input, selected when HP/LINE is held low
O
Sources current proportional to the junction temperature. Left floating for
normal operation.
O Left channel + output in BTL & SE mode
O Left channel – output in BTL mode & high-impedance in SE mode
O Right channel + output in BTL & SE mode
O Right channel – output in BTL mode & high impedance in SE mode
