Introduction

The Analog Devices ADAR4002 is a cutting-edge True Time Delay Unit (TDU) designed for high-frequency applications. Operating across a frequency range of 0.5GHz to 19GHz, this low-power integrated circuit offers programmable time delays and attenuation, making it an essential component for advanced communication systems.

Part Description

The ADAR4002 is a broadband, bidirectional, single-channel TDU and digital step attenuator (DSA). It features two programmable maximum time delays, each controlled by a 7-bit system, allowing for precise adjustments. The device operates in two ranges: Range 0 provides a maximum delay of 508ps with a resolution of 4ps, while Range 1 offers a maximum delay of 254ps with a finer resolution of 2ps. The DSA component of the ADAR4002 allows for attenuation adjustments from 0dB to 31.5dB with a step size of 0.5dB. With a compact 14-lead LFCSP package and a wide operating temperature range of -40°C to +85°C, this IC is built for reliability and performance in demanding environments.
