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.
