- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
- The TLV1544CD is a low-power, 10-bit successive approximation register (SAR) ADC with an internal sample-and-hold circuit.  
- It features a serial interface compatible with SPI, making it suitable for microcontroller-based applications.  
- The device operates over a wide supply voltage range, making it ideal for battery-powered and portable applications.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Built-in Analog Multiplexer:** Supports 4 single-ended input channels.  
- **Internal Reference Voltage:** Includes an on-chip reference for simplified design.  
- **SPI-Compatible Serial Interface:** Easy integration with microcontrollers.  
- **Wide Supply Voltage Range:** Operates from 2.7V to 5.5V.  
- **Small Footprint:** Available in a compact SOIC-16 package.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to Texas Instruments' official documentation.
