Цифровой вольтметр постоянного напряжения, основанный на время-импульсном методе. Генератор опорной частоты реализован на таймере 555, включенном в астабильном режиме. 16-ти разрядный ЦАП реализован на R-2R матрице. В качестве измеряемого напряжения используется источник постоянного напряжения в 2V. Количество импульсов прямо пропорционально измеряемому напряжению.

The Digital Voltmeter of DC-voltage that founded on time-impulse method. The frequency's generator realized on NEC 555 which included in astable mode. DAC has 16 bit and realized on R-2R matrix. The measured voltage is 2V source DC-voltage. Impulse's amount is in direct ratio at the measured voltage.
