Description and Introduction

12-Bit/ 3us/ 250kHz Sampling A/D Converter The LTC1272-8CCN is an 8-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 8-bit  
- **Sampling Rate:** 1.5 MSPS (Million Samples Per Second)  
- **Input Voltage Range:** 0V to VREF (typically 5V)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 75mW (typical)  
- **Package:** 20-pin PDIP (Plastic Dual In-Line Package)  
- **Interface:** Parallel  

### **Descriptions and Features:**  
- **High-Speed ADC:** Capable of 1.5 MSPS conversion rate.  
- **Low Power:** Operates at 75mW, making it suitable for power-sensitive applications.  
- **Single-Supply Operation:** Simplifies power requirements with a single +5V supply.  
- **On-Chip Sample-and-Hold:** Eliminates the need for an external sample-and-hold circuit.  
- **Internal Reference:** Includes a 2.5V reference, though an external reference can also be used.  
- **Wide Input Bandwidth:** Supports fast signal acquisition.  
- **Parallel Output:** Provides an 8-bit digital output for easy interfacing with microprocessors or logic circuits.  

This ADC is commonly used in applications requiring high-speed data acquisition, such as digital signal processing, instrumentation, and communications systems.
