OPERATION AS A DIVIDER

Figure 9 shows the connection required for division. Unlike

earlier products, the AD632 provides differential operation on

both the numerator and the denominator, allowing the ratio of

two floating variables to be generated. Further flexibility results

all dividers based on the use of a multiplier in a feedback loop,

the bandwidth is proportional to the denominator magnitude,

as shown in Figure 6.

The accuracy of the AD632 B-model is sufficient to maintain a

1% error over a 10 V to 1 V denominator range.
