was used and the supplies were ±9 V. The multiplier operates
from supplies between ±4.5 V and ±16.5 V.
Disconnecting Pin 9 and Pin 16 on the AD539 alters the
denominator in Equation 1 to 1 V, and the bandwidth is
approximately 10 MHz, with a maximum gain of 10 dB.
Using only Pin 9 or Pin 16 results in a denominator of 0.5 V,
a bandwidth of 5 MHz, and a maximum gain of 16 dB.
