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.
