Description
A1
I
SE/BTL
When this pin is Low , the audio amplifier is in differential mode. If a High level is applied, the configuration is in
SingleEnded Mode
A2
I
BYP
Bypass capacitor pin which provides the common mode voltage (VP/2).
A3
O
OUTB
Positive output of the amplifier. In high impedance state when the device is in SingleEnded mode.
B1
I
VP
Positive analog supply of the cell.
B2
NC
Not connected.
B3
I
VM
Ground.
C1
I
INM
Audio Input Signal.
C2
I
SD
The device enters in shutdown mode when a low level is applied to this pin.
C3
O
OUTA
Negative output of the amplifier. This is the active output dedicated to a SE load when this configuration is
activated.
