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
100MHz signal bandwidth (R_L = 50Ω) and a 22MHz control
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 (1.2µA). 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.
