PWM to Voltage Converter – PWM to Voltage Output DAC

PWM to Voltage Converter – PWM to Voltage Output DAC

The project presented here is a dual 12-bit PWM-to-voltage output DAC with high accuracy. The board is based on the LTC2644 chip. The LTC2644 measures the period and pulse width of the PWM input signals and updates the voltage output DACs after each corresponding PWM input rising...
