- **Compatibility:** Compliant with CCITT G.711/G.712 standards for PCM voice coding.  
- **Sampling Rate:** 8 kHz (standard telephony rate).  
- **Resolution:** 8-bit μ-law or A-law companding.  
- **Power Supply:** Typically operates on ±5V or single +5V supply.  
- **Package:** Available in plastic DIP (Dual In-line Package) or surface-mount options.  

### **Features:**  
- Integrated transmit (encoder) and receive (decoder) filters.  
- On-chip precision voltage reference.  
- Low power consumption.  
- Compatible with TTL/CMOS logic levels.  
- Includes built-in sample-and-hold circuitry.
