Description and Introduction

2 x 22 W stereo BTL car radio power amplifier with loudspeaker protection and 3-state mode switch The TDA1553CQ is an integrated circuit (IC) manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Type:** Audio Power Amplifier  
- **Package:** Multiwatt15 (15-pin)  
- **Output Power:** 2 x 22W (at 4Ω, THD = 10%) or 2 x 11W (at 8Ω, THD = 10%)  
- **Supply Voltage Range:** 6V to 18V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Total Harmonic Distortion (THD):** Typically 0.5% at 1W output  
- **Signal-to-Noise Ratio (SNR):** >70dB  
- **Gain:** Fixed at 26dB  

### **Descriptions:**
The TDA1553CQ is a dual-channel audio power amplifier designed for car radio and other audio applications. It features built-in protection circuits against short circuits, thermal overload, and reverse polarity. The IC operates in Class-B amplification mode and is optimized for low distortion and high efficiency.

### **Features:**
- **Dual-Bridge Amplifier:** Can drive two speakers independently.  
- **Mute/Standby Function:** Allows power-saving modes.  
- **Short-Circuit Protection:** Safeguards the IC from damage.  
- **Thermal Overload Protection:** Shuts down the amplifier if overheating occurs.  
- **Low External Component Count:** Simplifies circuit design.  
- **Reverse Polarity Protection:** Prevents damage from incorrect power supply connections.  

This information is based on the manufacturer's datasheet for the TDA1553CQ.

Application Scenarios & Design Considerations

2 x 22 W stereo BTL car radio power amplifier with loudspeaker protection and 3-state mode switch

Alternative Part Number

  • TDA1554Q --: Same 12W dual/quad BTL audio amplifier family from the original Philips/NXP line, pin-compatible in most applications and widely available.
  • TDA8560Q --: Similar class-B car audio power amplifier with BTL outputs, suitable replacement where slightly higher output power is acceptable.
  • LM1875T --: Popular 20W audio power amplifier IC from a different vendor, usable as a functional substitute with minor circuit adjustments.
  • TDA1552Q --: Closely related 2x22 W class-B audio amplifier in the same TDA155x series, electrically compatible in most circuits with only minor output-power differences.
  • TDA7377 --: Alternative dual/quad bridge car-radio amplifier from a different manufacturer and series, offering comparable supply voltage and output power for similar audio amplifier designs.
