ADC/DAC Resolution Converter

Every measurement system today uses ADCs (Analog-to-Digital Converters) and DACs (Digital-to-Analog Converters).
This ADC/DAC Resolution Converter helps you convert between: Digital value → Voltage & Voltage → Digital value. Simply enter bit resolution and reference voltage — perfect for Arduino, ESP32, STM32, PLCs, and instrumentation systems.

Bits to Voltage & Voltage to Bits Calculator

Mode 1: Bits → Voltage
1. Enter resolution (e.g., 10-bit).
2. Enter reference voltage (Vref).
3. Enter digital value from ADC/DAC.
4. Calculator outputs analog voltage.
Mode 2: Voltage → Bits
1. Enter resolution.
2. Enter reference voltage.
3. Enter analog voltage.
4. Calculator outputs digital bit value.

🧭 How to Use

FAQ

Q1. What is ADC resolution?

A. The number of bits that define how many digital steps the converter can output.

Q2. Does this work for DACs as well?

A. Yes — same formula applies in reverse.

Q3. What is Vref?

A. The maximum voltage the ADC/DAC can measure or output.

Q4. What microcontrollers use this logic?

A. Arduino, ESP32, STM32, AVR, PIC, ARM Cortex, PLC modules — all use similar conversion formulas.
