Description and Introduction

14-Bit/ 2.2Msps/ Sampling A/D Converter The LTC1414CGN is a high-performance, 14-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:** 14-bit  
- **Sampling Rate:** 1.25 MSPS (Million Samples Per Second)  
- **Input Voltage Range:** ±2.5V (Differential or Single-Ended)  
- **DNL (Differential Non-Linearity):** ±0.5 LSB (max)  
- **INL (Integral Non-Linearity):** ±1.0 LSB (max)  
- **SNR (Signal-to-Noise Ratio):** 82 dB (typ)  
- **THD (Total Harmonic Distortion):** -90 dB (typ)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 95 mW (typ)  
- **Operating Temperature Range:** 0°C to 70°C (Commercial Grade)  
- **Package:** 28-Lead SSOP  

### **Descriptions:**
- The LTC1414CGN is a high-speed, low-power 14-bit ADC designed for precision applications.  
- It includes an internal sample-and-hold (S/H) circuit for accurate signal acquisition.  
- The device supports both differential and single-ended input configurations.  
- It features a parallel digital output interface for easy integration with microprocessors or DSPs.  

### **Features:**
- **High-Speed Performance:** 1.25 MSPS throughput.  
- **Low Power:** Consumes only 95 mW at full speed.  
- **Wide Input Range:** ±2.5V differential or single-ended inputs.  
- **No Missing Codes:** Guaranteed over the full temperature range.  
- **Internal Reference:** Includes a 2.5V precision reference.  
- **Flexible Clocking:** Can be driven by an external or internal clock.  
- **Shutdown Mode:** Reduces power consumption when not in use.  
- **Compact Package:** 28-Lead SSOP for space-constrained designs.  

This ADC is suitable for applications such as data acquisition systems, medical imaging, communications, and industrial instrumentation.
