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, combined with a 750Ω bias resistor, ensuring 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; can be powered by just 3V when using only the 2.048V reference5. Compact size and easy wiring, suitable for electronics DIY, instrument debugging and equipment calibrationSpecifications:Supply voltage: 5V–12VOutput reference voltage: 2.048V, 4.096VVoltage accuracy: 0.1%Dimensions: 16.00 × 13.00 × 2.00 mmPackage list:Voltage Reference Adapter Module × 1Notes:1. This product is a voltage reference source, not a regulated power supply; the output cannot be switched off and is intended solely for measurement and calibration purposes.2. Please note that the actual colour of the product may vary slightly from the image due to monitor settings and lighting conditions.3. Manual measurements may result in dimensional tolerances of 1–2 cm, which is normal.
