Analog multipliers and dividers have become an increasingly important signal processing element in digital and analog electronic circuits. The AD538ADZ multipliers, dividers, and linear devices have become a popular choice, due to their low cost, high performance, and excellent reliability. This article provides an overview of the AD538ADZ application fields and working principles.

The AD538ADZ is a versatile voltage controlled current source (VCCS), which can be used as either an analog multiplier or a linear device. The device is designed to operate from + 9V to + 26V and has an adjustable output current of 65 mA. The AD538ADZ has a wide range of applications in a variety of fields, including automotive, communications, audio, and military/defense. In addition, it can also be used in medical, industrial, and transportation applications.

The AD538ADZ is used as an Analog Multiplier in applications that require scaling of the input signal or alogarithmic transformation of the input signal. As an analog multiplier the device provides an adjustable gain factor from -72 dB to +72 dB. The device utilizes a unique architecture that allows for a low-nonlinearity and an adjustable gain range of 0.25 to 4.0V/V. This feature makes the device ideal for a variety of signal conditioning applications such as precision control or communication interface.

The AD538ADZ can also be used as a Linear Device in applications that require a high input impedance. As a linear device the device provides an adjustable output impedance from 0 to -60dB. The device utilizes a unique architecture that allows for a low-nonlinearity and an adjustable resistance range of 0.3 to 10 kΩ. This feature makes the device ideal for impedance matching, impedance conversion, filtering, and low-frequency signal applications.

The AD538ADZ also includes an On-Off switch to control the gain and output of the device. When the On-Off switch is activated, the device will reduce its output impedance from 0 to -60dB. Once the On-Off switch is activated, the device will automatically adjust its output impedance to match the input signal. The device also provides an adjustable frequency response from -3 dB at 1kHz to -20dB at 10kHz.

The AD538ADZ is a versatile and reliable voltage controlled current source that offers a wide range of applications. The device is well suited for use in automotive, communications, audio, and military/defense applications, as well as in medical, industrial, and transportation applications. Its adjustable gain range and on-off switch make it an ideal choice for both analog multiplication and linear applications. The device offers exceptional performance with low-nonlinearity, high input impedance, and an adjustable output impedance.
