Description and Introduction

30W BTLX2CH AUDIO POWER AMPLIFIER The TA8221AL is an integrated circuit (IC) manufactured by Toshiba. Below are the factual specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Audio Power Amplifier IC  
- **Package:** SIP (Single In-line Package) or similar variant  
- **Power Supply Voltage (VCC):** Typically operates at **9V to 18V** (check datasheet for exact range)  
- **Output Power:** Up to **5.8W per channel** (at 13.2V, 4Ω, THD = 10%)  
- **Number of Channels:** **2 (Stereo)**  
- **Total Harmonic Distortion (THD):** Low distortion (specific value depends on conditions)  
- **Standby Function:** Includes mute/standby control  

### **Descriptions:**  
The TA8221AL is a **dual-channel (stereo) audio power amplifier IC** designed for car audio systems, portable stereos, and other consumer audio applications. It provides moderate output power with low distortion and includes built-in protection circuits.  

### **Features:**  
- **Dual-channel BTL (Bridge-Tied Load) amplifier**  
- **Low pop noise during power-on/off**  
- **Built-in thermal shutdown protection**  
- **Standby/mute function**  
- **Wide operating voltage range** (suitable for automotive applications)  
- **Minimal external components required**  

For exact electrical characteristics, pin configurations, and application circuits, refer to the official **Toshiba TA8221AL datasheet**.

Alternative Part Number

  • LM386N-4 --: Widely available low-voltage audio power amplifier in DIP package, commonly used as a substitute for small audio amplifier ICs like the TA8221AL.
  • TDA2822M --: Dual low-voltage audio power amplifier in DIP-8, a popular and inexpensive alternative for general-purpose audio amplification applications.
  • UTC8227L --: Audio power amplifier IC with similar function and pin-compatible footprint, often used as a direct replacement for Toshiba TA-series audio amplifiers.
  • TDA2003 --: Class AB audio power amplifier in a 5-pin package, widely used as a substitute for Toshiba TA-series audio amplifiers in low-power audio output stages.
  • LM383 --: Similar audio power amplifier IC with comparable output power and supply range, commonly cross-referenced for TA8221AL audio applications.
  • TDA2030A --: Higher-power Class AB audio amplifier offering comparable or better output capability, suitable as an upgrade substitute when pinout is adapted.
