Application Information
Theory of Operation
The HA-2547 is a current output, two quadrant multiplier with
one differential signal channel, V
differential control channel, V
detailed functional block diagram of the HA-2547. The
differential voltages of channels V
differential currents. These differential currents are then
multiplied in a circuit similar to a Gilbert Cell multiplier,
producing a differential current product. The differential
product currents are then converted to a single-ended output
current which is typically 2mA, ±20% at full scale (V
