VFC320BG

电压 - 频率和频率 - 电压转换器 Voltage-to-Frequency and Frequency-to-Voltage CONVERTER

DESCRIPON

The VFC320 monolithic voltage-to-frequency and frequency-to-voltage converter provides a simple low cost method of convert ing analog signals into digital pulses. The digital output is an open collector and the digital pulse train repetition rate is proportional to the amplitude of the analog input voltage. Output pulses are compatible with TTL, and CMOS logic families.
