Description and Introduction

20-Bit No Latency ADCs with Differential Input and Differential Reference The LTC2435-1CGN is a high-performance, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Resolution:** 24-bit  
- **Input Type:** Differential  
- **Input Voltage Range:** ±VREF (programmable)  
- **Reference Voltage:** External (supports up to 5V)  
- **Conversion Rate:** 3.5Hz (default), adjustable via external oscillator  
- **Noise-Free Resolution:** Up to 23 bits  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SSOP (GN)  

### **Descriptions and Features:**  
- **High Accuracy:** Provides 24-bit resolution with no missing codes.  
- **Low Noise:** Achieves high noise-free resolution for precision measurements.  
- **Flexible Input Range:** Differential input with programmable gain (PGA not integrated).  
- **Internal Oscillator:** Includes an onboard oscillator for standalone operation.  
- **Single-Cycle Settling:** Delivers accurate readings in a single conversion cycle.  
- **SPI-Compatible Interface:** Easy integration with microcontrollers and digital systems.  
- **Low Power Consumption:** Operates at 200µA (typical) in active mode.  
- **Auto-Calibration:** Eliminates offset and full-scale errors.  

The LTC2435-1CGN is designed for applications requiring high-resolution data acquisition, such as industrial sensors, medical instrumentation, and precision weigh scales.
