The ΔΣ ADC is constructed from a ΔΣ modulator and a digital filter. The modulator converts the analog input into a digital bit stream, while the digital filter translates the bit stream into a data word that represents the magnitude of the analog input…
It’s been three weeks since we launched “The Hub” here on E2E, and we’re already branching off into new and exciting areas. Today we kicked off a sister blog on Planet Analog called the “ Precision Hub ” with a blog post from…

Engineers like to simplify the design process using many rules to get the design going in the right direction before optimizations occur. One of my favorites is to always drive the inputs of an analog…
“ A clever person solves a problem. A wise person avoids it. ” – Albert Einstein
Albert Einstein would have loved analog design – there is always an element of relativity involved. For example, in data acquisition systems, accuracy is relative…
Other Parts Discussed in Post: TPS7A49 My colleague Collin Wells recently completed a blog series about 2-wire 4-20mA transmitters and their associated design challenges. The series concluded with a look at isolation schemes for 2-wire transmitters as…

Last week, I replaced the carpet in my house with wooden flooring. After removing the carpet from the staircase in our living room, I noticed my “uniform” staircase…
My previous posts discussed the basics of 4-wire transmitters and showed circuit-level design options for output and power-isolated 4-wire sensor transmitters. In this post, I’ll cover the final isolation configuration for 4-wire sensor transmitters …
Other Parts Discussed in Post: ADS1118 Thermal noise in analog design is almost always parasitic and should be avoided at all costs. Input filtering, PCB layout and grounding are paramount to good analog system designs, but you’ll always find some amount…
Other Parts Discussed in Post: STRIKE Welcome to part three of this blog series discussing electromagnetic compatibility (EMC) testing. In parts one and two we discussed the background of certification testing and the specifications for ESD and radiated…
