HA-2547
100MHz, Quadrant, Current Output, Analog Multiplier
Description
HA-2547 monolithic, high speed, quadrant, analog multiplier constructed Harris' Dielectrically Isolated High Frequency Process. high frequency performance HA-2547 rivals best analog multipliers currently available including hybrids. single-ended current output HA-2547 100MHz signal bandwidth 22MHz control input bandwidth. High bandwidth distortion make this part ideal component video systems. suitability precision video applications demonstrated further multiplication error (1.6%), feedthrough (-50dB), differential inputs with bias currents (1.2µA). HA-2547 also well suited mixer circuits well applications sonar, radar, medical imaging equipment. current output HA-2547 allows achieve higher bandwidths than voltage output multipliers. internal feedback resistor provided give accurate current-to-voltage conversion trimmed give full scale output voltage ±5V. HA-2547 limited multiplication applications only; frequency doubling power detection also possible.
