† In the SOIC package, the maximum RMS output power is thermally limited to 350 mW; 700 mW
peaks can be driven, as long as the RMS value is less than 350 mW.
‡ The D and DGN packages are available taped and reeled. To order a taped and reeled part, add
the suffix R to the part number (e.g., TPA701DR).
Terminal Functions

DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
BYPASS
2
I
BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected to
a 0.1-
µF to 2.2-µF capacitor when used as an audio amplifier.
GND
7
GND is the ground connection.
IN –
4
I
IN – is the inverting input. IN – is typically used as the audio input terminal.
IN+
3
I
IN + is the noninverting input. IN + is typically tied to the BYPASS terminal.
SHUTDOWN
1
I
SHUTDOWN places the entire device in shutdown mode when held high (IDD = 1.5 nA).
VDD
6
VDD is the supply voltage terminal.
VO+
5
O
VO+ is the positive BTL output.
VO–
8
O
VO– is the negative BTL output.

§ Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
