HA2556/883
July 1994
Wideband Four Quadrant Analog Multiplier (Voltage Output)
Description
The HA-2556/883 is a monolithic, high speed, four quadrant, analog multiplier constructed in 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-2556/883 provides a 450V/µs output 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.
