Analog Devices AD834 Four-Quadrant Multiplier Data Sheet
The AD834 is a monolithic, laser-trimmed four-quadrant analog multiplier intended for high-frequency applications. It features differential inputs and outputs, offering low distortion and performance that is relatively insensitive to temperature and supply variations due to stable band gap reference biasing.
In multiplier modes, the typical total full-scale error is 0.5%. The device provides a transconductance bandwidth in excess of 500 MHz from either of the differential voltage inputs when configured with a 50 Ω load. Outputs appear as a differential pair of currents at open collectors.
