Description and Introduction

DC / DC Converter For Electric Tuning (3V USE) The TA8126S is a monolithic integrated circuit (IC) designed for FM/AM radio applications. Below are its key specifications, descriptions, and features based on available information:

### **Manufacturer:**  
- Toshiba (originally)  

### **Specifications:**  
1. **Operating Voltage:**  
   - **FM Mode:** 1.8V to 6.0V  
   - **AM Mode:** 1.8V to 6.0V  

2. **Current Consumption:**  
   - **FM Mode:** 5.5mA (typical at 3V)  
   - **AM Mode:** 3.5mA (typical at 3V)  

3. **Frequency Range:**  
   - **FM:** 76MHz to 108MHz  
   - **AM:** 530kHz to 1,710kHz  

4. **Intermediate Frequency (IF):**  
   - **FM IF:** 10.7MHz  
   - **AM IF:** 450kHz  

5. **Sensitivity:**  
   - **FM:** 1.5μV (typical at 30dB S/N)  
   - **AM:** 50μV/m (typical at 20dB S/N)  

6. **Output Power:**  
   - Audio output capable of driving a headphone or speaker via an external amplifier.  

7. **Package:**  
   - **Type:** 24-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**  
- The TA8126S is a low-voltage FM/AM radio receiver IC with built-in RF amplifiers, mixers, IF amplifiers, detectors, and audio preamplifiers.  
- It supports both FM and AM demodulation with minimal external components.  
- Designed for portable radio applications due to its low power consumption.  

### **Features:**  
1. **Integrated FM/AM Tuner:**  
   - Single-chip solution for FM and AM reception.  

2. **Low Voltage Operation:**  
   - Works efficiently at voltages as low as 1.8V.  

3. **Low Current Consumption:**  
   - Optimized for battery-powered devices.  

4. **Built-in AGC (Automatic Gain Control):**  
   - Ensures stable reception under varying signal conditions.  

5. **Internal AFC (Automatic Frequency Control):**  
   - Helps maintain stable FM tuning.  

6. **Audio Output:**  
   - Provides demodulated audio output for external amplification.  

7. **Minimal External Components:**  
   - Reduces circuit complexity and cost.  

8. **Compact SSOP Package:**  
   - Suitable for space-constrained designs.  

This information is based on the original datasheet and technical documentation for the TA8126S. For precise application details, consult the official datasheet.
