Working Principles

The MAX152EAP is a voltage-to-frequency converter that generates an output frequency proportional to the input voltage. It utilizes a precision voltage-controlled oscillator (VCO) to achieve accurate conversion. The input voltage is compared with a reference voltage, and the resulting difference is used to control the VCO's frequency. The output frequency is directly related to the input voltage, allowing for precise measurement or control applications.
