Overview
NS4871 is a Class AB bridge-tied-load audio power amplifier. Its application circuit is simple, requiring minimal external components. No external coupling capacitors, bootstrap capacitors, or snubber networks are needed at the output. The ESOP-8 package makes it well-suited for portable systems. The NS4871 can enter a low-power shutdown mode via a control pin to reduce power consumption. It offers a gain-bandwidth product of up to 2.5MHz and is stable at unity gain. The amplifier's voltage gain can be adjusted by configuring external resistors, providing ease of use in applications.
Applications
- Laptop computers
- Desktop computers
- Low-voltage audio systems
Key features
- Voltage range: 3.0V - 5.25V
- Output power: 2.5W (RL = 4Ω, THD = 10%)
- Low shutdown leakage current: 1uA (typical)
- High-level shutdown
- ESOP-8 package
- Externally adjustable gain
- No output coupling capacitor, bootstrap capacitor, or snubber network required
- Unity-gain stable
