Tổng quan
Description
- Compact & Efficient: Small form factor with low power consumption, suitable for portable devices.
- Adjustable Frequency: Allows tuning to avoid interference with local FM stations.
- Stereo Support: Delivers clear, high-quality audio transmission.
- Easy Integration: Simple interface (e.g., audio input, power, and antenna connection) for quick prototyping.
Common applications include car audio systems, wireless microphones, and DIY FM transmitters. For optimal performance, ensure proper antenna placement and minimal signal interference.
Equivalent
- PAM8403 (3W stereo)
- TPA2012 (1.7W mono)
- HT6871 (3W mono)
- NS4150 (3W mono)
- XPT8871 (3W mono)
These chips offer similar power output (1W–3W) and operate at low voltage (2.5V–5.5V). Check pin compatibility and specs before substitution.
Features
- Output Power: Up to 3W (at 5V, 4Ω load).
- Efficiency: High efficiency Class-D operation (up to 90%).
- Supply Voltage: 2.5V–5.5V (ideal for battery-powered devices).
- Low Quiescent Current: 2.5mA (saves power in standby).
- Shutdown Mode: Ultra-low current (<0.1μA) when disabled.
- Thermal & Short-Circuit Protection: Built-in safeguards.
- Minimal External Components: Simple design integration.
- PSRR: >60dB (reduces power supply noise).
- Package: SOP-8 (compact footprint).
Commonly used in portable speakers, toys, and IoT devices.
Pinout
- Pins 1 & 16 (INP/INN): Differential audio input.
- Pins 2 & 3 (VREF/BYP): Reference voltage and bypass capacitor connection.
