Description and Introduction

Call progress monitor for line powered telephone sets The TEA1083 is a telephone speech and dialing circuit manufactured by PHILIPS. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage:** 3.5V to 6V  
- **Current Consumption:** Typically 1.5mA (standby mode)  
- **Operating Temperature Range:** -25°C to +75°C  
- **Package:** 16-pin DIP (Dual In-line Package)  

### **Descriptions:**
- Designed for use in telephone sets with pulse or tone dialing.  
- Integrates speech transmission, reception, and dialing functions.  
- Compatible with both electret and dynamic microphones.  
- Includes an adjustable sidetone suppression circuit.  

### **Features:**
1. **Speech Network:**  
   - Balanced microphone amplifier.  
   - Adjustable sidetone cancellation.
