Description and Introduction

12-Bit, 125Msps Low Power 3V ADCs The LTC2253IUH is a high-performance, 12-bit analog-to-digital converter (ADC) manufactured by **Linear Technology (now part of Analog Devices)**. Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Resolution:** 12-bit  
- **Sampling Rate:** 25 MSPS (Mega Samples Per Second)  
- **Input Type:** Differential  
- **Input Voltage Range:** 2 Vpp (peak-to-peak)  
- **Power Supply:** 1.8 V (analog and digital)  
- **Power Consumption:** 72 mW (typical)  
- **SNR (Signal-to-Noise Ratio):** 70.5 dB (typical)  
- **SFDR (Spurious-Free Dynamic Range):** 88 dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-Lead QFN (5mm × 5mm)  

### **Descriptions:**
- The LTC2253IUH is a **low-power, high-speed ADC** designed for applications requiring high dynamic performance.  
- It features a **differential pipeline architecture** with a digital error correction circuit for accurate 12-bit conversion.  
- The device includes an internal **sample-and-hold circuit** and supports a **1.8V CMOS-compatible** output interface.  
- It is **RoHS-compliant** and suitable for industrial, communications, and instrumentation applications.  

### **Features:**
- **Low Power:** 72 mW at full speed  
- **High Dynamic Performance:** Excellent SNR and SFDR  
- **Wide Input Bandwidth:** Supports high-frequency signals  
- **Flexible Digital Outputs:** 1.8V CMOS, DDR (Double Data Rate) LVDS (optional in other variants)  
- **Integrated Shutdown Mode:** Reduces power consumption when inactive  
- **Small Footprint:** 32-lead QFN package for space-constrained designs  

For exact performance under specific conditions, refer to the official **datasheet** from Analog Devices (formerly Linear Technology).
