电压 - 频率转换器 Voltage-to-Frequency Converters
Description
The RC4152 is a monolithic circuit containing all of the active components needed to build a complete voltage-to frequency converter. Circuits that convert a DC voltage to a pulse train can be built by adding a few resistors and capacitors to the internal comparator, one-shot, voltage reference, and switched current source. Frequency-to-voltage convert ers FVCs and many other signal conditioning circuits are also easily created using these converters.
