by KlausST, supermoderator on EDABoard.com Here I’d like to show how to design a DAC controlled high -side constant current source. Since it is often used as 0..20mA (or 4..20mA) current loop interface, we will focus on the interface requirements. * low speed ( maybe some 10Hz up to some kHz) * high precision * […]

Rad-hard 14-bit ADC optimized for apps in space
Renesas is excited to introduce the ISL73141SEH ADC, delivering the industry’s highest performance for radiation-hardened space applications. The ISL73141SEH ADC is one of the key signal-path building blocks in long-duration geosynchronous/geostationary Earth orbit (GEO) communication satellites and manned spacecraft, including lunar space missions. By delivering the industry’s best dynamic and static performance, the new 14-bit […]
High-side switch ICs optimized for automotive applications
ROHM has announced the development of a new family of four AEC-Q100 qualified high side switch ICs targeting the automotive market. Available in both 1- and 2-channel variants with RDS(on) ratings of 45mΩ, 70mΩ and 90mΩ, these IPDs (Intelligent Power Devices) incorporate multiple protection functions, ranging from overcurrent protection (OCP) and thermal shutdown (TSD) to […]
Advanced IC integrates instrumentation amp, auto-trimming, digital pots, analog switches
Dialog Semiconductor plc announced the SLG47004, Dialog’s first Advanced Analog GreenPAK IC. The SLG47004 integrates an instrumentation amplifier with auto-trimming, digital pots, analog switches, and a myriad of digital functions with in-system programmability in a small 3mm x 3mm solution size allowing designers to create simulate and prototype their own unique sophisticated analog ICs in […]
Filters, Part 1: Analog, switched, and digital filters
Filters are essential functions in most circuits and systems; as frequencies extend into the multi-GHz range, surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters are needed to meet the design objectives. An engineer I worked with (and whose name I have forgotten) once remarked to about electronic filters (and he was serious): “like […]
Analog multiplexers capable of switching signal voltages up to 36 V
Diodes Incorporated announced the introduction of the PS508 and PS509 analog multiplexers that are capable of switching signal voltages of up to 36V in an industrial environment. The high voltage capability of the devices will support industrial IoT (IIoT) applications using multiple sensors, including factory automation and process control, battery monitoring systems, and test and […]
