Product Introduction

Overview

The AD835AR-REEL, produced by Analog Devices Inc., is a four-quadrant, voltage output analog multiplier. It is fabricated on an advanced dielectrically isolated complementary bipolar process, offering high speed and versatility. The AD835 provides the linear product of its X and Y voltage inputs, with a unique summing feature at the Z input that allows for additional signal processing capabilities. This component is designed for simplicity, requiring minimal external components, and is particularly suited for applications that demand fast multiplication, division, and other signal processing functions.
