September 1998 File Number 2862.3
100MHz, Quadrant, Current Output, Analog Multiplier
HA-2547 monolithic, high speed, quadrant, analog multiplier constructed Intersil's 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-tovoltage conversion trimmed give full scale output voltage ±5V. HA-2547 limited multiplication applications only; frequency doubling power detection also possible.

Theory Operation
HA-2547 current output, quadrant multiplier with differential signal channel, differential control channel, VX-. Figure shows detailed functional block diagram HA-2547. differential voltages channels converted differential currents. These differential currents then multiplied circuit similar Gilbert Cell multiplier, producing differential current product. differential product currents then converted single-ended output current which typically 2mA, ±20% full scale ±5V). trimmed internal scaling resistor, designed convert output current accurate voltage grounding (pin 10). trimmed such that full scale output current voltage drop across will ±5.0V.

HA-2547 will operate over range supply voltages, ±15V. supply voltages below ±12V will cause degradation electrical parameters.
Offset Adjustment
signal channel offset voltage nulled using potentiometer between VYIO Adjust pins connecting wiper Reducing signal channel offset voltage will reduce feedthrough improve multiplication error.
