This converter is used in electro-measuring equipment, appliance engineering and chromatography. It has an expanded linear dynamic range. It contains a voltage-frequency converter (1), connected to a logic for conversion control (2), to whose inlet are connected a programmable frequency divider (3) and a logic for enhanced sensitivity control (7), while to its outlets are linked a synchronous programmable counter (5), a parallel register-memory (6), a second programmable frequency divider (8) and a logic for controlling the counting regime (9). A tact generator (4) is connected to the two programmable frequency dividers (3 and 8), while the second frequency divider (8) is connected to the parallel register-memory. A scheme for sensitivity control (10) is connected to the counting regime's control logic.
