Demo: One chip, multiple LTE signals for 3G, 4G, and 5G macro cell TDD base station work

August 24, 2018 By Lee Teschler

Matt Purvis from ADI recently took us through a demo of a super-wideband RF transceiver chip that targets the expanding 5G telecom area. The point of the chip is to transmit multi-carrier LTE signals and to simplify the task of designing MIMO systems. Called the ADRV9009, it is a single-chip time division duplex (TDD) design […]

Step-down DC/DC controller draws only 9 µA quiescent, targets burst-mode battery apps

July 11, 2018 By Jillian Zavoda

LTC3894 Step-down DC/DC controller

Analog Devices announces the Power by Linear LTC3894, a high voltage step-down DC/DC controller that draws only 9µA quiescent current with the output enabled in Burst Mode operation. Its wide 4.5V to 150V input voltage range can effectively eliminate the need for external surge suppression devices. The LTC3894’s 100% duty cycle capability and externally adjustable power good window […]

Synchronous step-down switcher delivers 95% efficiency at 2 MHz, emits little EMI

June 21, 2018 By Anna Casey

Synchronous step-down switcher

Analog Devices announces the Power by Linear™ LT8642S, a 10A, 18V input synchronous step-down switching regulator. Its Silent Switcher® 2 architecture uses two internal input capacitors as well as internal BST and INTVCC capacitors to minimize the area of the hot loops. The LT8642S dramatically reduces EMI emissions as a result of its controlled switching edges and its internal […]

Teardown: The Apple Sport watch

September 29, 2017 By Lee Teschler

Apple recently came out with the Series 3 version of its watch. We can get an idea of how the Series 3 goes together from a teardown analysis of Apple’s earlier Sport model. The Sport model we analyzed has an aluminum case but the watch is also available in stainless steel. It measures about 39 […]

Managing EV batteries squeezed into odd shapes

August 7, 2017 By Lee Teschler

Automakers are forced to fit EV batteries into nooks and crannies in an effort to maximize driving range. The resulting convoluted layouts call for a wireless approach to managing cells. GREG ZIMMER | Linear Technology Corp., now part of Analog Devices Inc. Lithium-Ion batteries require considerable care if they are expected to function reliably over […]

Rugged RS485 transceiver meets IEC Level 4 ESD standard

June 29, 2017 By Maddie Lippert

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC2862A, an enhanced version of the widely accepted LTC2862 ±60V tolerant RS485/RS422 transceiver that released several years ago. Both of these half-duplex transceivers eliminate field failures without the need of costly external protection devices by protecting practical RS485 systems from installation cross-wiring faults, ground […]
