PMIC - V/F and F/V Converters

The AD537SH/883B is a family of voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converters from Analog Devices. It boosts conversion accuracy and reduces power consumption to improve efficiency in applications where minimal power is available. This converter is featured in a wide range of commercial, industrial, medical, and military applications, due to its consistent performance, dependability, and reliability in harsh environments.

Features and Benefits

This converter combines AccuRateVoltage-to-Frequency conversion and AccuRateFrequency-to-Voltage Conversion technologies with low power consumption. Its AccuRate™ V/F frequency stability helps reduce system calibration and maintain accuracy, even when subjected to line and load transients. The device is provided in an 8-pin SOIC package, making it compatible with all kinds of surface mount components. The operating temperature range of –55°C to +125°C makes it suitable for use in extreme or industrial environments.

Application Fields

The AD537SH/883B is an ideal solution for sensor applications that require low power, high accuracy, and extreme temperature ranges. It is suitable for applications such as process controllers, thermometers, strain gages, and pressure transducers. This converter is also suitable for other applications involving a variety of analog signals, such as measuring current, frequency, rotation speed, or frequency phase. Furthermore, this converter is used in motor and actuator control systems, where feedback is necessary to ensure accurate operation of the motor or actuator.

Working Principle

The AD537SH/883B converter has two main components: a V/F and an F/V component. The voltage-to-frequency component changes an input voltage into a frequency output, while the frequency-to-voltage component converts a frequency input into an output voltage.The V/F component works by applying an input voltage to a voltage-controlled oscillator. This oscillator measures the input voltage and converts it into a frequency, which is then outputted.The F/V component works by applying a frequency input to a frequency-controlled oscillator. This oscillator measures the frequency, and then calculates the corresponding output voltage.

Conclusion

The AD537SH/883B is a versatile and reliable V/F and F/V converter that can be used in a variety of applications to improve system efficiency and accuracy. Its low power consumption and robust design make it suitable for use in harsh environments, while its AccuRate™ V/F frequency stability helps maintain accuracy, even when exposed to extreme temperatures. Its wide range of applications make it an ideal choice for embedded systems and other industrial installations.
