Attenuate: Divider Designer

Calculate, Analyze, and Design Precise Voltage Dividers.

Attenuate is a precision utility for engineers, students, and hobbyists designed to simplify the process of selecting resistor pairs for voltage divider circuits. Whether you are shifting logic levels or scaling sensor inputs, this tool provides the data needed to build reliable circuits.
Find the Best Resistor Pairs Stop guessing or calculating manually. Enter your input and target output voltages, and Attenuate instantly identifies the closest matching resistor pairs from the standard E24 series. Each result displays the actual output voltage and the precise error percentage, helping you choose the most accurate combination for your project.

Analyze Real-World Performance Ideal circuits rarely exist in practice. Attenuate goes beyond simple calculations with specialized analysis tools:
• Load Correction: Determine how your output voltage will change once a device is connected. Simply input your load resistance to see the impact on your divider’s performance.
• Power & Safety: Avoid component failure. Calculate the current and power dissipation for each resistor and view recommended wattage ratings based on a safety margin.

Streamlined Engineering Workflow
• Common Presets: Quickly access frequently used voltage conversions, such as 5V to 3.3V or 12V to 5V, with a single tap.
• Intuitive Design: A clean, focused interface that puts your data front and center.
• Full-Screen Experience: Optimized for the latest devices with a fluid, edge-to-edge layout that makes data entry and reading easier than ever.
• Personalized Appearance: Choose the look that suits your environment with light, night, and system-default theme options.

Build your next circuit with confidence. Attenuate provides the calculations, you provide the creativity.
