Description and Introduction

Low voltage telephone transmission circuit with dialler interface and regulated strong supply The TEA1114A is a telephone transmission circuit manufactured by PHILIPS. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Supply Voltage Range:** 3.5V to 12V  
- **Operating Temperature Range:** -25°C to +75°C  
- **Power Dissipation:** 500 mW (max)  
- **Package Type:** DIP16 (Dual In-line Package, 16 pins)  

### **Descriptions:**  
- The TEA1114A is designed for use in telephone sets, providing essential functions such as speech transmission, sidetone suppression, and line voltage regulation.  
- It includes a built-in voltage regulator to stabilize the supply voltage for the microphone amplifier and other internal circuits.  
- The IC supports both pulse and tone dialing compatibility.  

### **Features:**  
- **Microphone Amplifier:** Includes a preamplifier for the microphone input.  
- **Sidetone Suppression:** Reduces feedback between the microphone and earpiece.  
- **Line Voltage Regulation:** Maintains stable operation under varying line conditions.  
- **Low Power Consumption:** Suitable for energy-efficient telephone designs.  
- **Compatibility:** Works with both pulse and DTMF (Dual-Tone Multi-Frequency) dialing methods.  

This information is derived from the manufacturer's datasheet and technical documentation.
