TPA4861
SLOS163C – SEPTEMBER 1996 – REVISED JUNE 2004
1-W MONO AUDIO POWER AMPLIFIER
1-W BTL Output (5 V, 0.11 % THD+N)
3.3-V and 5-V Operation
No Output Coupling Capacitors Required
Shutdown Control (IDD = 0.6 A)
Uncompensated Gains of 2 to 20 (BTL Mode)
Surface-Mount Packaging
Thermal and Short-Circuit Protection
High Supply Ripple Rejection Ratio (56 dB at
1 kHz)
LM4861 Drop-In Compatible
The TPA4861 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average
power into an 8-
load at 0.2% 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 the amplifier are a shutdown function for power-sensitive applications as well as internal thermal and
short-circuit protection. The TPA4861 works seamlessly with TI's TPA4860 in stereo applications. The amplifier
is available in an 8-pin SOIC surface-mount package that reduces board space and facilitates automated
assembly.
