TPA4860
SLOS164B – SEPTEMBER 1996 – REVISED JUNE 2004
1-W MONO AUDIO POWER AMPLIFIER
1-W BTL Output (5 V, 0.2 % THD+N)
3.3-V and 5-V Operation
No Output Coupling Capacitors Required
Shutdown Control (IDD = 0.6 A)
Headphone Interface Logic
Uncompensated Gains of 2 to 20 (BTL Mode)
Surface-Mount Packaging
Thermal and Short-Circuit Protection
High Power Supply Rejection(56-dB at 1 kHz)
LM4860 Drop-In Compatible
The TPA4860 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average
power into an 8-
load at 0.4 % THD+N from a 5-V power supply in voiceband frequencies (f < 5 kHz). A BTL
configuration eliminates the need for external coupling capacitors on the output in most applications. Gain is
externally configured by means of two resistors and does not require compensation for settings of 2 to 20.
Features of this amplifier are a shutdown function for power-sensitive applications as well as headphone
interface logic that mutes the output when the speaker drive is not required. Internal thermal and short-circuit
protection increases device reliability. It also includes headphone interface logic circuitry to facilitate headphone
applications. The amplifier is available in a 16-pin SOIC surface-mount package that reduces board space and
facilitates automated assembly.
