SLOS316C – JUNE 2000 – REVISED JUNE 2004
These devices have limited built-in ESD protection. The leads should be shorted together or the device
placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

In the D package, the maximum 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.,
TPA741DR).

DESCRIPTION
NAME
NO.
BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected

to a 0.1-F to 2.2-F capacitor when used as an audio amplifier.
GND
7
GND is the ground connection.
IN-

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 for SE operations.
SHUTDOWN

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.

See the Texas Instruments document, PowerPAD Thermally Enhanced Package Application Report
(SLMA002), for more information on the PowerPAD package. The thermal data was measured on a
PCB layout based on the information in the section entitled Texas Instruments Recommended Board
