This unique circuit below can be used as divider and multiplier. This circuit is formed by all four sections of a 4136 . The Q1 through Q4 can be any PNP transistor, but that must matched transistors. The transistor matching determine the acurracy of the divider and multiplier circuit. Here is the schematic diagram of the circuit:

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 […]
