TPA4861 Overview
Key Specifications
Package: SOIC
Pins: 8
Max Voltage (typical range): 5.5 V
Min Voltage (typical range): 2.7 V
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.
Key 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)
