Description and Introduction

2 x 3 W stereo BTL audio output amplifier The TDA7057Q is a monolithic integrated audio amplifier manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Type:** Stereo BTL (Bridge-Tied Load) output amplifier  
- **Supply Voltage Range (VP):** 4.5V to 18V  
- **Output Power:**  
  - 2 × 6W (into 8Ω at 12V, THD = 10%)  
  - 2 × 4.5W (into 8Ω at 9V, THD = 10%)  
- **Total Harmonic Distortion (THD):** Typically 0.5% (at Po = 1W, RL = 8Ω, f = 1kHz)  
- **Gain:** Fixed at 40dB (internally set)  
- **Signal-to-Noise Ratio (S/N):** >70dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DBS17P (17-pin DIP)  

### **Descriptions:**  
- The TDA7057Q is designed for portable audio applications such as TVs, radios, and multimedia systems.  
- It features two independent BTL amplifiers, eliminating the need for external coupling capacitors.  
- The amplifier has built-in protection against short circuits and thermal overload.  
- No external components are required for volume control as it includes an internal DC volume control.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Provides higher output power without requiring an output capacitor.  
- **Low External Component Count:** Requires minimal external components for operation.  
- **Mute Function:** Includes a standby/mute mode for power saving.  
- **Thermal Protection:** Automatically shuts down in case of overheating.  
- **Short-Circuit Proof:** Protected against output short circuits to ground or supply voltage.  

This information is based on the official datasheet from PHILIPS/NXP.

Application Scenarios & Design Considerations

2 x 3 W stereo BTL audio output amplifier

Alternative Part Number

  • LM4950TA --: Audio power amplifier in a similar power class with bridge-tied load output, suitable as a functional substitute in many audio driver circuits.
  • TDA7266 --: Dual audio power amplifier with comparable supply voltage and output power range, commonly used as a replacement in similar audio applications.
  • TDA2822M --: Low-voltage dual audio power amplifier widely available and often used where a compact stereo amplifier replacement is needed, though power rating is lower.
  • LM4755T --: Dual audio power amplifier in a TO-220 package with similar output power and supply range, suitable as a functional replacement for the TDA7057Q in many audio applications.
  • TDA7265 --: Dual-channel audio power amplifier IC with comparable output power and voltage ratings, widely used as a substitute in TV and audio equipment.
  • TDA7377 --: Multi-channel audio power amplifier offering similar performance and supply voltage, commonly used as an alternative in audio amplifier designs.
  • TDA7057AQ --: Same TDA7057 audio amplifier family from the original Philips semiconductor business (now NXP), with the A variant offering improved characteristics and direct pin compatibility for most applications.
  • TDA7056B --: Similar BTL audio power amplifier in the TDA705x series with comparable supply voltage and output power, suitable as a functional substitute where slightly lower output power is acceptable.
