Description and Introduction

Low Power 14-Bit/ 400ksps Sampling ADC Converter with Serial I/O The LTC1417AIGN 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 Type:** Single-ended or differential  
- **Input Voltage Range:** ±2.5V (adjustable)  
- **DNL (Differential Nonlinearity):** ±1 LSB (max)  
- **INL (Integral Nonlinearity):** ±1.5 LSB (max)  
- **SNR (Signal-to-Noise Ratio):** 80 dB (typ)  
- **THD (Total Harmonic Distortion):** -90 dB (typ)  
- **Power Supply:** Single +5V  
- **Power Consumption:** 95 mW (typ)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions:**
- The LTC1417AIGN is a high-speed, low-power ADC with excellent DC accuracy and AC performance.  
- It features a high-impedance input buffer, eliminating the need for external drive circuitry.  
- The device includes a built-in sample-and-hold (S/H) circuit for accurate signal acquisition.  
- It supports both single-ended and differential input configurations.  

### **Features:**
- **High-Speed Performance:** 1.25 MSPS throughput  
- **Low Power:** 95 mW typical power consumption  
- **No Missing Codes:** Guaranteed 14-bit resolution  
- **Flexible Input Range:** Adjustable ±2.5V input range  
- **Internal Reference:** Includes a 2.5V precision reference  
- **Parallel Interface:** Easy interfacing with microprocessors and DSPs  
- **Pin-Compatible Upgrade:** Compatible with 12-bit LTC1410  

This ADC is suitable for applications requiring high-speed, high-resolution data conversion, such as medical imaging, communications, and industrial instrumentation.  

(Note: Always refer to the official datasheet for the most accurate and updated information.)
