HA2557/883

Wideband Four Quadrant Analog

Multiplier (Current Output)

Description

The HA-2557/883 is a monolithic, high speed, four quadrant,

analog multiplier constructed in Intersil’ Dielectrically Iso-

lated High Frequency Process. The single-ended current

output of the HA-2557/883 has a 130MHz signal bandwidth

an ideal component in video systems.

The suitability for precision video applications is demon-

strated further by low multiplication error (1.5%), low

feedthrough (-52dB), and differential inputs with low bias cur-

rents (8

µA). The HA-2557/883 is also well suited for mixer

circuits as well as AGC applications for sonar, radar, and

medical imaging equipment.

The current output of the HA-2557/883 allows it to achieve

higher bandwidths than voltage output multipliers. Full scale out-

put current is trimmed to 1.6mA. An internal 2500

Ω feedback

resistor is also provided to accurately convert the current, if

desired, to a full scale output voltage of

±4V. The HA-2557/883 is

not limited to multiplication applications only; frequency doubling,

power detection, as well as many other configurations are also

possible.
