PIN DESCRIPTION
Pin Type Symbol Description
A1 I INM Negative input of the first amplifier, receives the audio input signal. Connected to the
feedback resistor R
f
and to the input resistor R
in
.
A2 O OUTA Negative output of the NCP2892. Connected to the load and to the feedback resistor Rf.
A3 I INP Positive input of the first amplifier, receives the common mode voltage.
B1 I VM_P Power Analog Ground.
B2 I VM Core Analog Ground.
B3 I V
p
Positive analog supply of the cell. Range: 2.2 V−5.5 V.
C1 I BYPASS Bypass capacitor pin which provides the common mode voltage (Vp/2).
C2 O OUTB Positive output of the NCP2892. Connected to the load.
C3 I SHUTDOWN The device enters in shutdown mode when a low level is applied on this pin.
