Description

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

analog multiplier constructed in Harris’ Dielectrically Isolated

High Frequency Process. The single-ended current output of

High bandwidth and low distortion make this part an ideal

component in video systems.

The suitability for precision video applications is demon-

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

feedthrough (-50dB), and differential inputs with low bias

currents (8

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

cuits as well as AGC applications for sonar, radar, and med-

ical imaging equipment.

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

bandwidths than voltage output multipliers. Full scale output

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 is

not limited to multiplication applications only; frequency dou-

bling and power detection are also possible.

For MIL-STD-883 compliant product consult the HA-2557/883

datasheet.
