Description and Introduction

Speech and handsfree IC with auxiliary inputs/outputs and analog multiplexer The TEA1099H is a telephone speech and line interface circuit manufactured by PHILIPS.  

### **Specifications:**  
- **Function:** Telephone speech and line interface circuit  
- **Manufacturer:** PHILIPS  
- **Technology:** Integrated circuit (IC)  
- **Package:** Typically available in DIP or SO packages (exact package depends on variant)  
- **Operating Voltage:** Designed for standard telephone line voltage (typically 48V DC, with ringing signals up to ~90V AC)  
- **Features:** Includes line interface, speech processing, and hybrid functions for full-duplex communication  

### **Descriptions and Features:**  
- Provides a complete interface between the telephone line and the speech circuit in a handset or terminal.  
- Includes a balanced line driver and receiver for two-wire to four-wire conversion (hybrid function).  
- Features sidetone cancellation to improve voice clarity.  
- Supports DTMF (Dual-Tone Multi-Frequency) signaling for dialing.  
- Includes automatic gain control (AGC) for consistent audio levels.  
- Designed for use in analog telephones, answering machines, and similar communication devices.  

(Note: Exact electrical characteristics may vary; refer to the datasheet for detailed parameters.)
