Featuring the company’s analogML core—a fully analog machine learning processor […]
A comparison of EMI test setups and specifications for automotive, industrial and defense applications, part 2: Radiated emissions
By Timothy Hegarty, Applications Engineer, Texas Instruments This article compares electromagnetic compatibility (EMC) requirements in automotive, industrial and defense product family standards, specifically various test parameters, test equipment, test setups and test methods for radiated emissions (REs). Much like the treatment of conducted emissions [1] in part 1 of this two-part article series, the […]
Keeping the noise down
By Patrik Kalbermatten, KEMET Compact nanocrystalline single-phase filters that suppress electromagnetic interference from the power provide engineers with greater design flexibility. In our increasingly connected world, we are ever more dependent on electronic equipment and devices and the semiconductors contained within. It is perhaps no surprise, then, to find that demand for components that […]
Basics of audio filters
By Diksha Nama, contributor, Engineers Garage An audio system is designed to receive audio signals (via microphone), record audio in some storage, transmit audio (through wired or wireless communication channels), and reproduce audio signals (via speakers). So, the audio circuits perform signal processing for representing the sound in the form of electrical signals, manipulate the […]
Analog precision measurement ICs feature low power dissipation
Designers can now achieve double the battery life together with robust protection and highest accuracy for the internet of things (IoT), industrial and healthcare applications with three new Essential Analog ICs from Maxim Integrated Products, Inc.: MAX41400 instrumentation amplifier, MAX40108 precision operational amplifier, and MAX31343 real-time clock (RTC) with integrated MEMS oscillator. When designing IoT and battery-operated sensors, engineers […]
What is the difference between current feedback and voltage feedback op amps?
Current feedback (CFB) operational amplifiers (op amps) and voltage feedback (VFB) op amps have almost as many similarities as differences. CFBs and VFBs both have inverting and non-inverting inputs, a signal output, inputs for positive and negative voltage supplies and use feedback and gain resistors to stabilize circuit operation and set circuit gain. That can […]
Electrical noise can come from anywhere
Any unwanted signal that’s combined with the desired signal is called noise. In any circuit, noise can come from anywhere; from external systems as well as from within a circuit itself. External sources include a number of sources such as power lines, RF transmitters, nearby conductors, ignition systems, or motors that turn on and off […]
Two-wire, hall effect switches operate over -40 C to 150 C
Diodes Incorporated has announced a family of automotive-compliant, two-wire unipolar (AH323xQ/4xQ) and latch (AH327xQ/8xQ) switch integrated circuits (ICs) that provide high sensitivity and high stability over wide operating voltage and temperature ranges. The ICs are for use in automotive proximity- and position-sensing applications, including seatbelt buckle, power window, gear selector, and seat position. The adoption […]
Designing a DAC-controlled, high-side constant current source
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 * […]
