DescriptionThe HA-2557/883 is a monolithic, high speed, four quadrant, analog multiplier constructed in Intersil' Dielectrically Isolated High Frequency Process. The single-ended current output of the HA-2557/883 has a 130MHz signal bandwidth (RL = 50). 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 (1.5%), low feedthrough (-52dB), and differential inputs with low bias currents (8mA). 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 output current is trimmed to 1.6mA. An internal 2500W 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.
