Description and Introduction

20-Bit No Latency Delta Sigma ADCs with Differential Input and Differential Reference The LTC2431IMS is a high-performance 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 24 bits  
- **Input Type:** Differential  
- **Input Voltage Range:** ±VREF (programmable)  
- **Reference Voltage:** External (supports up to 5V)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Conversion Rate:** Programmable (1.7Hz to 3.5Hz)  
- **Noise Performance:** 0.5μVRMS (at 1.7Hz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead MSOP  

### **Descriptions:**  
The LTC2431IMS is a low-noise, high-resolution ADC designed for precision measurement applications. It features an integrated oscillator, eliminating the need for an external clock. The device includes a flexible differential input and operates with a wide supply voltage range, making it suitable for battery-powered and industrial systems.  

### **Features:**  
- **No Latency:** Provides accurate conversions without settling time.  
- **Internal Oscillator:** No external clock required.  
- **Programmable Data Rate:** Adjustable conversion speed.  
- **Low Power Consumption:** 200μA (typical) at 3V.  
- **SPI-Compatible Serial Interface:** Easy interfacing with microcontrollers.  
- **Auto-Calibration:** Eliminates offset and full-scale errors.  
- **Direct Sensor Interface:** Works with thermocouples, RTDs, and bridge sensors.
