DYNAMIC CHARACTERISTICS
The closed loop frequency response of the AD532 in the multi-
plier mode typically exhibits a 3 dB bandwidth of 1 MHz and
rolls off at 6 dB/octave thereafter. Response through all inputs is
essentially the same as shown in Figure 7. In the divide mode,
the closed loop frequency response is a function of the absolute
value of the denominator voltage as shown in Figure 8.
Stable operation is maintained with capacitive loads to 1000 pF
in all modes, except the square root for which 50 pF is a safe
upper limit. Higher capacitive loads can be driven if a 100 Ω
resistor is connected in series with the output for isolation.

POWER SUPPLY CONSIDERATIONS
Although the AD532 is tested and specified with ± 15 V dc
supplies, it may be operated at any supply voltage from ± 10 V
to ± 18 V for the J and K versions, and ± 10 V to ± 22 V for the
S version. The input and output signals must be reduced pro-
portionately to prevent saturation; however, with supply voltages
below ± 15 V, as shown in Figure 9. Since power supply sensitiv-
ity is not dependent on external null networks as in other
conventionally nulled multipliers, the power supply rejection
ratios are improved from 3 to 40 times in the AD532.
NOISE CHARACTERISTICS
All AD532s are screened on a sampling basis to assure that
output noise will have no appreciable effect on accuracy. Typi-
cal spot noise vs. frequency is shown in Figure 10.
