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 the HA-2557 has a 130MHz signal bandwidth (RL = 50Ω). 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 (8µA). The HA-2557 is also well suited for mixer circuits as well as AGC applications for sonar, radar, and med ical imaging equipment.
