HA-2547

100MHz, Two Quadrant,

Current Output, Analog Multiplier

The HA-2547 is a monolithic, high speed, two quadrant,

analog multiplier constructed in Intersil’s Dielectrically

Isolated High Frequency Process. The high frequency

performance of the HA-2547 rivals the best analog

multipliers currently available including hybrids.

The single-ended current output of the HA-2547 has a

input bandwidth. High bandwidth and low distortion make this

part an ideal component in video systems. The suitability for

precision video applications is demonstrated further by low

multiplication error (1.6%), low feedthrough (-50dB), and

differential inputs with low bias currents (1.2

µA). The HA-2547

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-2547 allows it to achieve higher

bandwidths than voltage output multipliers. An internal

feedback resistor is provided to give an accurate current-to-

voltage conversion and is trimmed to give a full scale output

voltage of

±5V. The HA-2547 is not limited to multiplication

applications only; frequency doubling and power detection

are also possible.
