Product Description
- DESCRIPTION
- The TPA4861 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average power into an 8-Ω 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.
- FEATURES
- • 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 µA)
- • 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
