### **Descriptions:**  
The LTC2498CUHF#PBF is a high-precision, low-noise ADC designed for applications requiring high-resolution measurements. It features an integrated oscillator, eliminating the need for an external crystal or clock. The device includes a flexible input multiplexer that supports both single-ended and differential inputs.  

### **Features:**  
- **High Accuracy:** 24-bit resolution with no missing codes  
- **Flexible Input Configuration:** Supports 16 single-ended or 8 differential channels  
- **Integrated Oscillator:** No external clock required  
- **Low Noise:** Optimized for precision sensor measurements  
- **Wide Supply Range:** Operates from 2.7V to 5.5V  
- **I²C Interface:** Easy communication with microcontrollers  
- **Built-In PGA (Programmable Gain Amplifier):** Optional 2x, 4x, 8x, or 16x gain  
- **50Hz/60Hz Rejection:** Built-in digital filtering for noise immunity  

This ADC is commonly used in industrial, medical, and instrumentation applications where high-resolution signal acquisition is critical.
