Analog multiplication is a fundamental operation in many electronic systems such as differential amplifiers, logarithmic amplifiers, sample-and-hold circuits, and AGC (automatic gain control) systems. The AD539SD/883B is an integrated circuit multiplier/divider designed to perform these functions within the limits of its linear precision operating range. It allows almost any input voltage to be multiplied or divided by any other input voltage within the operating limits of the device.

The AD539SD/883B linear-analog multiplier/divider offers differential input and outputs, two-quadrant multiplication and division, and fifty gain ranges. This allows it to be used as a building block in many different applications. The device is also low in noise and power consumption and offers a wide dynamic range.

One of the most common applications for the AD539SD/883B is in differential amplifiers. As inputs are multiplied and the differential output is determined, the initial input signal can be drastically amplified for applications such as data acquisition. This low-cost IC may also be used as a sample-and-hold circuit, providing an adjustable trigger for sample-and-hold processes. It could also be used in AGC systems, or in logarithmic amplifiers.

In terms of operation, the AD539SD/883B is composed of two internal linear circuitry amplifiers which perform the desired multiplication or division operation. The multiplication operation is obtained through the following formula: VOUT = (V1 x V2)/VSS. The division operation follows this formula: VOUT = (V1/V2) x VSS. Where V1 and V2 are the two input voltages and VSS is an adjustable reference voltage.

In order to improve gain linearity and to reduce the variations between devices, the AD539SD/883B includes an on-chip reference voltage generator. The voltage generated is accurate to within 0.5 % and its value is determined by a single external resistor, thus making the operation of the device quite simple.

The AD539SD/883B was designed to be a low-cost and low-noise multiplier/divider that can be used in a wide range of applications. Its linear precision operating range allows it to be used as a building block in any analog design, from simple data acquisition systems to AGC circuits and logarithmic amplifiers. Its on-chip reference voltage generator ensures repeatable performance, even when used in different applications.
