DESCRIPTION

The MPY634 is a wide bandwidth, high accuracy, fourquadrant

analog multiplier. Its accurately laser-trimmed

multiplier characteristics make it easy to use in a wide

variety of applications with a minimum of external parts,

often eliminating all external trimming. Its differential X, Y,

and Z inputs allow configuration as a multiplier, squarer,

divider, square-rooter, and other functions while maintaining

high accuracy.

The wide bandwidth of this new design allows signal

processing at IF, RF, and video frequencies. The internal

output amplifier of the MPY634 reduces

design complexity compared to other high frequency multipliers

and balanced modulator circuits. It is

capable of performing frequency mixing, balanced modulation,

and demodulation with excellent carrier rejection.

An accurate internal voltage reference provides

precise setting of the scale factor. The differential Z input

allows user-selected scale factors from 0.1 to 10 using

external feedback resistors.
