AD835 - Analog Devices

AD835 4-Quadrant Multiplier

The AD835 is a complete four-quadrant, voltage output analog multiplier, fabricated on an advanced dielectrically isolated complementary bipolar process. It generates the linear product of its X and Y voltage inputs with a −3 dB output bandwidth of 250 MHz (a small signal rise time of 1 ns). Full-scale (−1 V to +1 V) rise to fall times are 2.5 ns (with a sta.

Features

Simple: basic function is W = XY + Z Complete: minimal external components required Very fast: Settles to 0.1% of full scale (FS) in 20 ns DC-coupled voltage output simplifies use High differential input impedance X, Y, and Z inputs Low multiplier noise: 50 nV/√Hz APPLICATIONS Very fast multiplication, division, squaring Wideband modulation and demodulation Phase detection and measurement Sinusoidal frequency doubling Video gain control and keying Voltage-controlled amplifiers and filters GENERAL DESCRIPTION The AD835 is a complete four-quadrant, voltage output analog multiplier, fabricated on.
