Class-D audio amplifier The TDA8932BT is a class-D audio amplifier manufactured by NXP Semiconductors. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:
### **Specifications:**
- **Output Power:** Up to 2 × 15 W (4 Ω, THD = 10%) or 1 × 30 W (BTL mode, 8 Ω, THD = 10%).
- **Supply Voltage Range:** 10 V to 36 V (single supply).
- **Efficiency:** Typically > 90% (minimizes heat dissipation).
- **THD+N (Total Harmonic Distortion + Noise):** < 0.1% (typical).
- **Signal-to-Noise Ratio (SNR):** > 100 dB (A-weighted).
- **Operating Temperature Range:** -40°C to +85°C.
- **Package:** HSOP24 (PowerSO36 variant also available).
### **Descriptions:**
- The TDA8932BT is a high-efficiency class-D audio amplifier designed for high-quality audio applications.
- It operates in either stereo (2-channel) or mono (Bridged Tie Load, BTL) mode.
- The device includes built-in protection features such as over-temperature, short-circuit, and overvoltage protection.
- It is suitable for applications like flat-panel TVs, home audio systems, and portable speakers.
### **Features:**
- **High Efficiency:** Class-D operation reduces power loss.
- **Flexible Configuration:** Can be used in stereo or mono BTL mode.
- **Low Standby Power:** < 1 mW in mute mode.
- **Integrated Protections:**
- Over-temperature shutdown.
- Short-circuit protection.
- Overvoltage protection.
- **Minimal External Components:** Reduces PCB footprint and cost.
- **Low EMI Emission:** Complies with international standards.
