TEXAS INSTRUMENTS VFC32KUE4 电压频率转换器, 500 kHz, 10kHz 至 100kHz, 0.05 %, ± 11V 至 ± 20V, SOIC, 14 引脚
The is a Voltage-to-Frequency and Frequency-to-Voltage Converter provides an output frequency accurately proportional to its input voltage. The digital open-collector frequency output is compatible with all common logic families. Its integrating input characteristics give the VFC32 excellent noise immunity and low nonlinearity. Full-scale output frequency is determined by an external capacitor and resistor and can be scaled over a wide range.
