Description and Introduction

15ppm/C Max/ 100UA/ SOT23-3 SERIES VOLTAGE REFERENCE **Precision Voltage Reference for Demanding Applications: REF3140AIDBZT**  

In today’s high-performance electronic systems, accuracy and stability are non-negotiable. The **REF3140AIDBZT** from Texas Instruments is a precision voltage reference designed to meet the stringent requirements of industrial, automotive, and instrumentation applications. With an initial accuracy of **±0.05%**, low temperature drift (**8ppm/°C**), and ultra-low noise, this component ensures reliable performance in critical environments.  

The REF3140AIDBZT delivers a fixed **4.096V** output, making it ideal for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and sensor interfaces where precise voltage levels are essential. Its low dropout voltage of **200mV** allows efficient operation even with minimal headroom, while the **1.5mA supply current** minimizes power consumption—crucial for battery-powered and energy-sensitive designs.  

Housed in a compact **SOT-23-3** package, this voltage reference combines space-saving convenience with robust performance. It features excellent line and load regulation, ensuring stable output despite input voltage fluctuations or varying load conditions. Additionally, the REF3140AIDBZT operates over a wide temperature range (**-40°C to +125°C**), making it suitable for harsh environments.  

Engineers seeking a dependable voltage reference will appreciate the REF3140AIDBZT’s combination of precision, efficiency, and durability. Whether used in medical devices, industrial control systems, or automotive electronics, this component delivers the accuracy and reliability needed for mission-critical designs.  

For applications demanding uncompromising performance, the **REF3140AIDBZT** stands out as a superior choice in voltage reference solutions.
