Description and Introduction

4-/8-Channel 24-Bit uPower No Latency ADCs The LTC2408IG is a high-performance, 24-bit analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 24-bit  
- **Input Channels:** 8 differential or 16 single-ended  
- **Input Voltage Range:** ±0.3V to ±2.5V (differential)  
- **Throughput Rate:** 3.5Hz (maximum)  
- **Noise Performance:** 0.6μVRMS (typ)  
- **Integral Nonlinearity (INL):** ±2ppm (max)  
- **Differential Nonlinearity (DNL):** ±1ppm (max)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Power Consumption:** 200μA (typ)  
- **Interface:** SPI-compatible  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead SSOP  

### **Descriptions and Features:**  
- **High Accuracy:** Provides 24-bit resolution with no missing codes.  
- **Low Noise:** 0.6μVRMS noise for precise measurements.  
- **Flexible Input Configuration:** Supports 8 differential or 16 single-ended inputs.  
- **Internal Oscillator:** Eliminates the need for an external clock.  
- **Single-Cycle Settling:** Ensures fast and accurate conversions.  
- **Internal Gain:** Optional 2x gain for low-level signal amplification.  
- **SPI Interface:** Simple serial communication with microcontrollers.  
- **Low Power:** Consumes only 200μA, making it suitable for battery-powered applications.  
- **Wide Supply Range:** Operates from 2.7V to 5.5V.  

The LTC2408IG is designed for high-precision applications such as industrial process control, weigh scales, and instrumentation.
