DESCRIPTION
The MPY600 is a wide-bandwidth four-quadrant
signal multiplier. Its output voltage is equal to the
algebraic product of the X and Y input voltages. For
signals up to 30MHz, the on-board output op amp
provides the complete multiplication function with a
low-impedance voltage output. Differential current
outputs extend multiplier bandwidth to 75MHz.
The MPY600 offers improved performance compared
to common semiconductor modulator or multiplier
circuits. It can be used for both two-quadrant (voltage-
controlled amplifier) and four-quadrant (double-
balanced) applications. While previous devices
required cumbersome circuitry for trimming, balance
and level-shifting, the MPY600 requires no external
components. A single external resistor can be used to
program the conversion gain for optimum spurious-
free dynamic range. When used as a modulator, carrier
feedthrough measures –60dB at 5MHz.
Differential X, Y and Z inputs can be connected in a
variety of useful configurations, including squarer,
divider, and square-rooter circuits. The MPY600 is
available in 16-pin plastic DIP, specified for the indus-
trial temperature range.
