Analog circuits interactive design tools & resources

An R-2R ladder DAC converts digital binary inputs into a corresponding analog voltage using a network of resistors arranged in a repeating R and 2R pattern.

Calculate resistor values, gain of Instrumentation amplifiers

Linear and low dropout regulators (LDOs) provide a stable output voltage from a higher input voltage, with LDOs operating efficiently even with a small input-to-output voltage difference.

Class D amplifiers use high-speed switching and PWM to achieve high-efficiency audio amplification, ideal for compact audio systems.

Ohm’s law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.

Calculate the values of resistor and capacitor of Sallen Key filters including low-pass, high-pass and band-pass filters.
