AD650KN is a voltage/frequency (V/F) and frequency/voltage (F/V) converter device manufactured by Analog Devices, Inc. It is a monolithic integrated circuit device with a single-supply operation from 2.5V to 11V and a wideband input/output range of 0 to 5MHz.The AD650KN is a frequency-to-voltage converter (F/V converters) designed to accept a wide range of input frequencies up to 5MHz and convert them into corresponding voltage outputs. It is built using a 76dB logarithmic amplifier circuit, followed by a precision integrator that forms the building block of its overall topology.The device comes with a low-scale frequency range of 0.01Hz up to a maximum of 5MHz. Its high accuracy and temperature stability of ±0.06% from −45°C to +105°C in its operating temperature range makes the AD650KN a reliable device for use in a variety of applications. The device also features an integrated precision reference circuit consisting of an ultra stable resistor and an amplifier configured to deliver an output voltage of 1.235V to the logarithmic amplifier section of the device. This voltage is used as a reference for generating the control voltage of the device and is also used as the TRIM. The AD650KN is used in a wide range of applications, such as industrial automation, frequency-to-analog signal conversion, data acquisition, robotics, servo motor control, closed-loop current control, power supplies, and many more.In industrial automation, the AD650KN is used in applications where measurements and periodic signals are needed. For example, it can be used to measure the rotational speed of a machinery. By providing a precise frequency input to the converter’s input, the corresponding voltage output can be used to provide accurate readings of the rotational speed.The device can also be used to control a servo motor in a robotic assembly line. The input frequency of the device is adjusted according to the desired angular position of the motor. The corresponding voltage output is used to control the angular position of the motor or perform position control of the motor.In other applications, such as power supplies, the AD650KN can be used to measure and monitor the output voltage or frequency of a power supply system. By measuring the output voltage of the power supply, the device can be used to provide a precise and reliable output voltage measurement. The AD650KN can also be used in closed-loop current control applications, such as those found in power supplies. By providing precise input frequencies, the device can be used to measure and monitor the output current of a power supply system. The voltage output of the AD650KN can then be used to control the output current of the power supply.In addition to its industrial applications, the AD650KN is also used in data acquisition applications. By providing precise input frequencies, the device is able to convert the frequency inputs into corresponding voltage outputs which can then be used to measure and monitor various physical parameters, such as temperature, pressure, and flow.The AD650KN offers wide input/output frequency ranges, an integrated precision reference circuit, and high accuracy and temperature stability. It is an ideal device for industrial automation applications such as frequency-to-analog signal conversion, closed-loop current control, robotic applications, and many more.
