Data Sheet AD532 FUNCTIONAL DESCRIPTION
The functional block diagram for the AD532 is shown in Figure 1 The product of the two inputs is resolved in the multiplier cel and the complete schematic in Figure 13. In the multiplying and using Gilbert’s linearized transconductance technique. The cell squaring modes, Z is connected to the output to close the feedback is laser trimmed to obtain VOUT = (X1 − X2)(Y1 − Y2)/10 V. The around the output op amp. In the divide mode, it is used as an built in op amp is used to obtain low output impedance and make input terminal. possible self contained operation. The residual output voltage offset The X and Y inputs are fed to high impedance differential can be zeroed at VOS in critical applications. Otherwise, the VOS pin amplifiers featuring low distortion and good common-mode should be grounded. rejection. The amplifier voltage offsets are actively laser trimmed to zero during production.
