Description and Introduction

24-Bit High Speed 8-/16-Channel Delta Sigma ADCs with Selectable Speed/Resolution The LTC2448CUHF#PBF 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-bit  
- **Channels:** 8 differential or 16 single-ended  
- **Input Type:** Differential/Single-ended  
- **Sampling Rate:** Up to 3.5kHz (programmable)  
- **Noise:** 600nV RMS at 1.7Hz, 800nV RMS at 3.5kHz  
- **INL (Integral Non-Linearity):** ±2ppm (max)  
- **Power Supply:** 2.7V to 5.5V  
- **Interface:** SPI-compatible  
- **Operating Temperature:** -40°C to +125°C  
- **Package:** 38-Lead QFN (5mm × 7mm)  

### **Descriptions:**  
The LTC2448CUHF#PBF is a high-precision, low-noise, multi-channel ADC with an integrated oscillator, eliminating the need for external components. It features a flexible input multiplexer, allowing differential or single-ended measurements. The device supports variable data rates and filter modes for optimal performance in different applications.  

### **Features:**  
- **High Accuracy:** 24-bit resolution with no missing codes.  
- **Programmable Speed/Noise Trade-off:** Adjustable output rates from 6.9Hz to 3.5kHz.  
- **Integrated Oscillator:** No external crystal required.  
- **Low Power:** 1.5mA typical current consumption.  
- **SPI Interface:** Easy interfacing with microcontrollers.  
- **Internal PGA (Programmable Gain Amplifier):** Supports gains of 1, 2, 4, 8, 16, 32, 64, or 128.  
- **Auto-Calibration:** Eliminates offset and full-scale errors.  

This ADC is suitable for industrial, medical, and instrumentation applications requiring high-resolution measurements.
