Built-in analog-to-digital converters
There are sensors for a plethora of smart applications that can measure a wide range of parameters (e.g., temperature, light, acceleration, pressure, proximity, etc.). The real world data is analog. Therefore sensors typically provide analog data in the form of voltage (e.g., 0V-5V) and most of the time this data is later transformed into digital […]

Analog Devices announces the Power by Linear™ LT8361, a current mode, 2MHz multitopology DC/DC converter with an internal 2A, 100V switch. It operates from an input voltage range of 2.8V to 60V, and is suitable for applications with input sources ranging from a single-cell Li-Ion battery to multicell battery stacks, automotive inputs, telecom power supplies […]
Considerations in PCB layout guidelines
A Printed Circuit Board (PCB) layout, in its most basic form, is a means to transfer a circuit from a breadboard to a more stable and permanent physical form. Whereas entire books and college coursework have been dedicated to PCB layout, what follows is a short overview of what to consider when making a PCB. […]

Step-down regulator operates from 24-to-48-V inputs, emits little EMI
Analog Devices announces the Power by Linear LTM4653, 58VIN step-down µModule Regulator. The LTM4653 can safely operate from unregulated or fluctuating 24V to 48V input supplies in noisy environments such as factory automation, industrial robotics, communication infrastructure and avionics systems. The LTM4653 integrates input and output filters in a package, enabling the device to meet the EN55022 […]
Power system manager combines digital measurements, PMBus interface computation
Analog Devices announces the Power by Linear LTC2972, a 2-channel power system manager, featuring current, power and energy monitoring of the intermediate bus input to point-of-load (POL) converters. Monitoring circuit board power and energy use is a prerequisite for managing, optimizing and reducing their consumption in order to lower server rack and data center cooling and […]
Boost regulator delivers wide input and output range and tiny footprint to optical modules
Analog Devices, Inc. announced the Power by Linear LTM4661, a low power step-up µModule regulator in a 6.25mm x 6.25mm x 2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm² single-sided or 0.5cm² on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, […]
Modern factories: Electromagnetic noise is replacing audible noise
by Rudy Ramos, Mouser Electronics In the past, factories were noisy places; in fact, noise-induced hearing loss was one of the most common occupational ailments in the USA. As the Industrial Internet of Things (IIoT) – sometimes termed Factory 4.0 – led to more electronics in factories, electromagnetic noise replaced audible noise. As the need for process […]
150-V dual synchronous step-down DC/DC controller eliminates external surge protection devices
Analog Devices announces the Power by Linear LTC7810, a high voltage non-isolated 150-V dual synchronous step-down DC/DC controller that drives all N-channel MOSFET power stages. Its 4.5V to 140V (150V abs max) input voltage range is designed to operate from a high input voltage or from an input that has high voltage surges, eliminating the need […]
