Free electronic circuit design and schematic diagram
The following schematic diagram shows us about the connections for square root mode for ADS532 analog processor chip. Similar to the division mode, the multiplier cell is connected in the feedback of the op amp by connecting the output back to both the X and Y inputs. To prevent latch up as Zi approaches 0 Volts, the diode D1 is […]

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 flip-flop circuit is a free running/astable multivibrator one, with bases and collector of both emitter biased transistor are directly coupled to each other. Switching action is supported by means of capacitor in each emitter circuit. This configuration produce a triangle waves at emitters. Since neither transistor can remain permanently cut off, then a free running oscillation will be generated. […]
