The AD534TD Linear - Analog Multipliers, Dividers, is a versatile circuit that provides multiplication, division, and various other operations. It also can be used to build more complex circuits such as a dynamic voltage amplifier. The AD534TD has a wide range of applications in many different fields and is particularly suitable for demanding applications, such as telecommunications, industrial process control, and embedded systems.

The AD534TD is a four-quadrant analog multiplier/divider, allowing for both multiplication and division of incoming signals. It has two differential inputs and one single-ended output, allowing for one input signal to be multiplied or divided by the other. The AD534TD is capable of multiplying and dividing ranges for input signals from -2.5 V to +2.5 V, with a gain from -1 to +1.

The AD534TD has inputs of two signal types. These are the signal input and the reference input. The signal input is the signal which will be multiplied or divided, while the reference input is the signal which is used to set the multiplier/divider’s gain. Both input signals can either be single-ended or differential, with the reference input being single-ended and the signal input being differential.

The AD534TD can be used in a wide range of applications, such as switch-mode audio amplifiers, dynamic voltage amplifiers, computer power supply design, telecommunications, video/audio recording, industrial process control and embedded systems. It is suitable for low noise applications, such as sample-and-hold circuits, where it can be used to multiple the voltage of a signal without introducing noise. It is also suitable for high gain applications, such as antenna amplifiers, where the gain can be precisely adjusted using the reference input.

The operation of the AD534TD is based on a closed loop technique. The reference input voltage is applied to a voltage-controlled amplifier (VCA) whose gain is connected to the feedback path of the differential amplifier. The output of the amplifier is then connected to the attenuator whose output is also connected to the VCA. The attenuator is used to set the gain of the multiplier. When the multiplier’s gain is set, the reference input voltage is applied to the multiplier and the signal input is applied to the reference input. The gain of the multiplier is then fixed and can not be changed, meaning the multiplier can only be used as a multiplier or divider. The output voltage of the multiplier/divider is then proportional to the product/quotient of the signal and reference inputs.

In summary, the AD534TD Linear - Analog Multipliers, Dividers, is a versatile circuit that provides multiplication, division, and various other operations. It is suitable for a wide range of applications in the telecommunications, industrial process control, and embedded systems. Its operation is based on a closed loop technique and it is capable of multiplying and dividing ranges for input signals from -2.5 V to +2.5 V, with a gain from -1 to +1.
