HA2557/883
July 1994
Wideband Four Quadrant Analog
Multiplier (Current Output)
Description
The HA-2557/883 is a monolithic, high speed, four quadrant,
analog multiplier constructed in Intersil鈥?Dielectrically Iso-
lated High Frequency Process. The single-ended current
output of the HA-2557/883 has a 130MHz signal bandwidth
(R
L
= 50鈩?. 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 (-52dB), and differential inputs with low bias cur-
rents (8碌A). 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鈩?feedback
resistor is also provided to accurately convert the current, if
desired, to a full scale output voltage of
卤4V.
The HA-2557/883 is
not limited to multiplication applications only; frequency doubling,
power detection, as well as many other con铿乬urations are also
possible.
