TPA4861
SLOS163C – SEPTEMBER 1996 – 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.

Terminal Functions
TERMINAL
I/O DESCRIPTION
NAME NO.
BYPASS is the tap to the voltage divider for internal mid-supply bias. This terminal should be connected to a
BYPASS 2 I
0.1-µF – 1.0-µF capacitor when used as an audio power 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 (I

(1) 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.
