Microchip Technology TC9400 Voltage-to-Frequency Converters

Microchip Technology TC9400 Voltage-to-Frequency Converters are low-cost Voltage-to-Frequency (V/F) converters that utilize low-power CMOS technology. These converters accept a variable input signal and generate an output pulse train. The V/F converters are also employed as highly accurate Frequency-to-Voltage (F/V) converters. The V/F or F/V converter system requires two additional capacitors, three resistors, and a reference voltage. Microchip Technology TC9400 Voltage-to-Frequency Converters are suitable for 13-bit ADCs, phase-locked loops, motor control, and FM demodulation.
