The HA-2556 is a monolithic, High-Speed, four quadrant, analog multiplier constructed in the Intersil Dielectrically Isolated High Frequency Process. The voltage output simplifies many designs by eliminating the current-to-voltage conversion stage required for current output multipliers. The HA-2556 provides a 450V/µs slew rate and maintains 52MHz and 57MHz bandwidths for the X and Y channels respectively, making it an ideal part for use in video systems. The suitability for precision video applications is demonstrated further by the Y-Channel 0. 1dB gain flatness to 5. 0MHz, 1. 5% multiplication error, -50dB feedthrough and differential inputs with 8µA bias current. The HA-2556 also has low differential gain (0. 1%) and phase (0. 1°) errors. The HA-2556 is well suited for AGC circuits as well as mixer applications for sonar, radar, and medical imaging equipment. The HA-2556 is not limited to multiplication applications only; frequency doubling, power detection, as well as many other configurations are possible.
