TPA4861
Overview
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.
- 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
- PACKAGE (TOP VIEW)
