DESCRIPTION
The MPY634 is a wide bandwidth, high accuracy,
four-quadrant 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.
