Description and Introduction

Single Chip 12-Bit Data Acquisition System The LTC1296DCN is a 12-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 12-bit  
- **Channels:** 8 single-ended or 4 differential  
- **Conversion Time:** 10µs (typical)  
- **Sampling Rate:** Up to 100ksps  
- **Input Voltage Range:** 0V to VREF (programmable)  
- **Reference Voltage:** External (2.5V to 5V)  
- **Supply Voltage:** Single +5V or dual ±5V  
- **Power Consumption:** 15mW (typical)  
- **Interface:** SPI/Microwire compatible  
- **Operating Temperature Range:** 0°C to 70°C (commercial grade)  
- **Package:** 16-pin PDIP (DIP-16)  

### **Descriptions:**  
The LTC1296DCN is a successive approximation register (SAR) ADC with an 8-channel multiplexer. It supports both single-ended and differential input configurations and communicates via a 3-wire serial interface (SPI-compatible).  

### **Features:**  
- **Low Power Consumption:** 15mW typical  
- **Flexible Input Configuration:** 8 single-ended or 4 differential channels  
- **No Missing Codes:** Guaranteed 12-bit performance  
- **Internal Sample-and-Hold:** Eliminates the need for external components  
- **Wide Supply Range:** Operates from a single +5V or dual ±5V supply  
- **SPI/Microwire-Compatible Serial Interface:** Easy integration with microcontrollers  
- **Built-In Multiplexer:** Simplifies multi-channel data acquisition
