TPA741DR

Texas Instruments · Audio Amplifiers · SOIC-8

TPA741DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SHUTDOWN	input	SHUTDOWN places the entire device in shutdown mode when held high.
2	BYPASS	passive	BYPASS is the tap to the voltage divider for internal mid-supply bias and should be connected to a 0.1-µF to 2.2-µF capacitor when used as an audio amplifier.
3	IN+	input	IN+ is the noninverting input and is typically tied to the BYPASS terminal for single-ended (SE) operation.
4	IN-	input	IN- is the inverting input and is typically used as the audio input terminal.
5	VO+	output	VO+ is the positive BTL output.
6	VDD	power_in	VDD is the supply voltage terminal, with an absolute maximum supply voltage of 6 V.
7	GND	power_in	GND is the ground connection.
8	VO-	output	VO- is the negative BTL output.
