HA2556/883
July 1994
Wideband Four Quadrant Analog
Multiplier (Voltage Output)
Description
The HA-2556/883 is a monolithic, high speed, four quadrant,
analog multiplier constructed in Intersil鈥?Dielectrically
Isolated High Frequency Process. The voltage output
simpli鏗乪s many designs by eliminating the current-to-voltage
conversion stage required for current output multipliers. The
HA-2556/883 provides a 450V/碌s output slew rate and
maintains 52MHz and 57MHz bandwidths for the X and Y
channels respectively, making it an ideal part for use in video
systems.
The suitability for precision video applications is
demonstrated further by the Y Channel 0.1dB gain 鏗俛tness
to 5.0MHz, 1.5% multiplication error, -50dB feedthrough and
differential inputs with 8碌A(chǔ) bias current. The HA-2556 also
has low differential gain (0.1%) and phase (0.1
o
) errors.
The HA-2556/883 is well suited for AGC circuits as well as
mixer applications for sonar, radar, and medical imaging
equipment. The HA-2556/883 is not limited to multiplication
applications only; frequency doubling, power detection, as
well as many other con鏗乬urations are possible.
