Voltage frequency converter circuit composed of AD654
The AD654 integrated circuit serves as the core of the voltage frequency converter, which is designed to convert an input voltage to a corresponding frequency output. The configuration of resistors (Rl) and capacitors (Cl) is critical, as they define the operating characteristics of the circuit, including the frequency range and the linearity of the output signal.
In operation, the input voltage is applied to the AD654, which processes this voltage and generates a frequency output that is proportional to the input. The relationship between the input voltage and the output frequency can be adjusted by selecting appropriate values for Rl and Cl. The circuit is capable of operating efficiently across a wide input voltage range, making it suitable for various applications where voltage-to-frequency conversion is required.
The maximum power consumption of 3mA indicates that the circuit is energy-efficient, making it suitable for battery-powered applications or situations where power conservation is essential. The ability to function effectively at a minimum supply voltage of 4.5V ensures that the VFC can be integrated into low-voltage systems without compromising performance.
Furthermore, the capability to achieve a maximum frequency of 520kHz allows for applications that require high-speed signal processing or data transmission. This makes the VFC circuit versatile for use in telecommunications, sensor interfacing, and other electronic systems where frequency modulation of voltage signals is necessary.
Overall, the low-cost voltage frequency converter utilizing the AD654 is an efficient and adaptable solution for converting voltage levels into frequency outputs, suitable for a wide range of electronic applications.The circuit shown in the figure is low-cost voltage frequency converter (VFC) with AD654. Connecting to necessary components Rl and Cl according to figure will make a VFC application circuit. Supply voltage can still guarantee performance to l6.5V when it is as low as 4.5V. The maximum power consumption is 3mA (no load). The highest frequency is 520kHz. The.. 🔗 External reference
