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.
