Description and Introduction

Dual Preamplifier The TA8162SN is a monolithic integrated circuit (IC) designed for FM/AM radio applications. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
- Toshiba Semiconductor (now part of Kioxia Holdings Corporation after restructuring).

### **Specifications:**  
- **Function:** FM/AM IF (Intermediate Frequency) amplifier and detector.  
- **Operating Voltage:** 2V to 7V (typical).  
- **Current Consumption:** ~5mA (low power consumption).  
- **Package:** 16-pin DIP (Dual Inline Package).  
- **Frequency Range:**  
  - **AM:** 455kHz IF.  
  - **FM:** 10.7MHz IF.  

### **Descriptions:**  
- Integrates FM and AM detection circuits, reducing external component count.  
- Suitable for portable radios due to low voltage operation.  
- Includes built-in AGC (Automatic Gain Control) for stable reception.  

### **Features:**  
1. **FM Section:**  
   - Limiter amplifier for FM IF.  
   - Quadrature detector for FM demodulation.  

2. **AM Section:**  
   - IF amplifier for AM signals.  
   - Diode-based AM detector.  

3. **Additional Functions:**  
   - AGC for both FM and AM.  
   - Low distortion and high sensitivity.  

For exact electrical characteristics, refer to the original Toshiba datasheet.

Application Scenarios & Design Considerations

Alternative Part Number

  • LM567CN --: Tone decoder IC with similar function to the TA8162SN; widely available and well documented.
  • NE567N --: Classic tone decoder in DIP package, functionally comparable and easy to source.
  • XR567CP --: Pin-compatible tone decoder alternative with similar electrical characteristics.
  • LA1265 --: AM/FM IF and detector IC with similar function and pinout, widely used as a substitute in radio tuner circuits.
  • TA8122AN --: Same Toshiba AM/FM radio IC family with comparable IF/detector functionality, though from a different series naming.
  • AN7224 --: AM/FM IF amplifier and detector IC offering equivalent radio front-end functions for tuner applications.
