Description and Introduction

24-Bit High Speed 8-/16-Channel Delta Sigma ADCs with Selectable Speed/Resolution The LTC2444CUHF#PBF is a high-speed, high-resolution delta-sigma analog-to-digital converter (ADC) manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Resolution:** 24-bit  
- **Sampling Rate:** Up to 4kHz (programmable)  
- **Input Channels:** 4 differential or 8 single-ended  
- **Input Voltage Range:** ±VREF (differential)  
- **Reference Voltage:** External (supports up to 5V)  
- **Interface:** SPI-compatible serial interface  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 38-Lead QFN (5mm × 7mm)  

### **Descriptions:**  
The LTC2444CUHF#PBF is a low-noise, high-accuracy ADC with an integrated oscillator, eliminating the need for an external crystal or clock source. It features a flexible input multiplexer, allowing differential or single-ended measurements. The device includes an onboard digital filter for noise reduction and supports multiple speed/resolution modes.  

### **Features:**  
- **High Resolution:** 24-bit no missing codes  
- **Programmable Speed/Resolution:** 6Hz to 4kHz output rate  
- **Low Noise:** 600nV RMS at 1.8kHz  
- **Internal Oscillator:** No external clock required  
- **Flexible Input Configuration:** 4 differential or 8 single-ended channels  
- **SPI Interface:** 3-wire or 4-wire mode  
- **Power-Down Mode:** Reduces power consumption when idle  

This ADC is suitable for precision measurement applications such as industrial process control, instrumentation, and data acquisition systems.
