This amplifier doesn't exist...now what!?
Xavier Ramus
05 24 2013 09:14 AM
Sometimes it’s impossible to find an amplifier with the right input and output characteristics, but a signal chain approach described in my previous blog posts on high gain, high bandwidth works well. Although very high gain can be achieved, one...

Cable equalization 101 – Automating your design
Hooman Hashemi
05 21 2013 05:47 PM
Judging by the number of views on a post related to numerical cable equalization , on the High Speed E2E forum (more than 3,700 at last count!), I would guess that it’s a pretty interesting topic for many folks. Since TI is one of the leading manufacturers...

RS-485 - Who says you can't teach an old dog new tricks?
Neel Seshan
05 17 2013 03:37 PM
Would you agree that RS-485 has turned out to be one of the most versatile communication standards when it comes to industrial applications? It’s very reliable for long distance communication and very popular. In all the years that the RS-485 standard...

Have you ever wondered how engineers designed active filters before the birth of software? They were able to do it using nomographs - but before we talk about what these are, let’s refresh our memory a little bit on active filters. Magnitude...

Let’s take this driver out for a spin
Soufiane Bendaoud
05 10 2013 04:09 PM
Before I suggest a suitable op amp to drive an ADC, I look at the application. This steers me toward one of two categories: low voltage or high voltage. If the system requires a low voltage operation, chances are I’ll look for a low power op...

Being negative can still be positive
Loren Siebert 1
05 07 2013 04:59 PM
The first operational amplifiers (op amps) used what is commonly called split power supplies, meaning the power for the amplifier was symmetrical around ground with both positive and negative polarities. Since most power supplies used transformers to...

Addressing those pesky European power consumption rulings
Dafydd Roche
05 03 2013 10:48 AM
This January, the European Commission implemented legislation to limit the power consumption in line-powered products when they are deemed in "standby" and "Off" mode. Traditionally, home audio products were guilty of wasting a...

DAC Essentials: String Theory
Kevin Duke

No, I'm not actually going to talk about particle physics today - though that would be cool...instead we'll be discussing the theory of the string DAC architecture. String theory! The string DAC, sometimes referred to as the Kelvin divider...

Current feedback amplifier...how do I make it work for me?
Xavier Ramus
04 26 2013 10:00 AM
Current feedback (CFB) amplifiers mostly belong in the realm of high speed amplifiers . There are lot of good application notes developed over the years that describe the operation and the main issues encountered when applying current feedback amplifiers...

Turn up the heat
Mont Taylor
04 24 2013 04:35 PM
More and more electronics are needed for very harsh environments, which then results in the need for multiple electronic components. For instance, oil and gas drilling, where temperatures reach up to 200°C require complete solutions for intelligent...
