PMIC - V/F and F/V ConvertersAD650JPZ operational amplifiers are widely applied in the field of power management integrated circuitry (PMIC). They can perform both voltage-to-frequency (V/F) and frequency-to-voltage (F/V) conversion. This versatile device can generate signals with voltages and frequencies that exceed the otherwise possible range of analog amplifiers, and can be used for measuring or controlling purposes.In a V/F converter, AD650JPZ will accept an analog voltage at its input and generate an output frequency based on that voltage. This output frequency then becomes proportional to the input voltage, once the scaling factor of the device is taken into account. This feature makes the AD650JPZ ideal for applications where a digital signal is required but only an analog source is available, such as systems measuring engine speed, as well as controlling industrial equipment.Similarly, when used as an F/V converter, AD650JPZ will accept a frequency input and generate an analog voltage on the output, proportional to the input frequency. This can be used for system control purposes, where the input of varying frequencies would correspond to different states of the system. This is useful in, for example, rotating machinery assembly, where the rotation speed of the motors must be controlled by a sensed frequency input.Both voltage-to-frequency and frequency-to-voltage conversion can also be used for measuring purposes. In addition to engine speed, the AD650JPZ can also be used for measuring or detecting the rate of flow, such as in a fuel or water delivery system. By measuring the frequency of the voltage output from the device and adjusting the flow rate accordingly, quick and accurate measurement of flow can be achieved.The device’s performance is further enhanced by the presence of the on-chip frequency compensation circuitry, which allows the AD650JPZ to maintain stable performance over a wide range of input frequencies. This circuitry also improves the transient response time of the device, allowing it to respond quickly to changing conditions.When used as a V/F converter, the AD650JPZ is capable of outputting frequencies up to 1 MHz, with a minimum frequency step size of 1 Hz, and a voltage range from 0 to 5 V. In F/V mode, the device can handle input frequencies up to 10 kHz, while outputting voltages up to 20 V. The versatile loop bandwidth on offer also ensures optimal response when used in feedback control applications.In conclusion, the AD650JPZ is a powerful and versatile PMIC device that can be used for both voltage-to-frequency and frequency-to-voltage conversion, making them ideal for applications in the field of industrial, automotive and medical electronics. With the added features of on-chip frequency compensation and an exceptionally wide input frequency range, the device is an invaluable component in the power-control arsenal of an engineer.
