Using the phase sensitive detector circuit below the magnitude of sinusoidal signal can be measured. Beside that, this circuit also can be used to measures 180°-out-of-phase inputs with proper polarity. But, it depends on the relationship to the reference with less than 1% error. This circuit uses a AD741J op amp. Here is the schematic diagram of the circuit and […]

We can build a divider circuit using only a single chip component, a special purpose integrated circuit AD532. We can configure the AD532 as a two quadrant divider by connecting the multiplier cell in the feedback loop of the op amp and using the Z terminal as a signal input, as shown in the following figure. For your note, the […]

The following schematic diagram shows a squaring circuit. Basically, this circuit is a simple variation of multiplier circuit. However, the differential input capability of the AD532 can be used to obtain a positive or negative output response to the input. This circuit has useful feature which is suitable for control applications, as it might eliminate the need for an additional […]

The AD532 should be connected as the following figure for operation as a multiplier. We can fed the input differentially to the X and Y inputs, or single ended by simply grounding the unused input. Connect the inputs according to the desired polarity in the output. To close the feedback loop around the op amp, the Z terminal is tied […]

The AD532 is the first pre-trimmed single chip monolithic multiplier/divider. This device guarantees a maximum multiplying error of +- 1% and a +-10 V output voltage without the need for any output op amp or external trimming resistors. It’s simplicity of use provides design engineers with an attractive alternative to modular multipliers because the AD532 is internally trimmed. The AD532 […]

This is an audio effect circuit that give extra oscillation to your guitar, percussive, or semi percussive instruments, you can call it a funk box. This guitar effect circuit is basically a damped oscillator that is set slightly below its critical oscillation point. The oscillator part is constructed by feeding back the output signal through a bandpass circuit, with the […]
