Aideepen | LM4040 Voltage Reference Source Board 2.048V 4.096V High-Precision Voltage Reference Module 0.1% Accuracy for Microcontroller

Features:1. Dual high-precision reference circuits in parallel, paired with a 750Ω bias resistor, ensure stable output with no drift2. Dual reference voltage outputs: 2.048V for 3.3V systems, 4.096V for 5V systems3. Overall accuracy as high as 0.1%, suitable for precision measurement and calibration of ADCs, multimeters, and microcontrollers4. Flexible power supply: Standard 5V–12V; 3V is sufficient when using only the 2.048V reference5. Compact size and easy wiring, suitable for electronics DIY, instrument debugging, and equipment calibrationProduct SpecificationsSupply Voltage: 5V–12VOutput Reference Voltage: 2.048V, 4.096VVoltage Accuracy: 0.1%Dimensions: 16.00 × 13.00 × 2.00 mmProduct Contents:1 moduleNotesThis product is a voltage reference source, not a regulated power supply. The output cannot be turned off and is intended solely for measurement and calibration purposes.Please note that the actual color of the product may vary slightly from the image due to monitor settings and lighting conditions. We appreciate your understanding.Manual measurements may result in dimensional errors of 1–2 centimeters, which is normal.
