Other Parts Discussed in Post: OPA211 , OPA320 In helping to select op amps and instrumentation amps I frequently hear the comment, “I need really high input impedance.” Oh really?… are you sure?
It’s rare that input impedance, or more specifically…
If you follow this blog, you most likely have heard of TI Designs – Precision , our library of high-quality reference designs for precision applications. The first thing you’ll see on the TI Designs – Precision homepage is a graphic illustrating the three…
Did you see last week’s resistor puzzle? Check it out if you missed it . Here’s the solution:
We’re not accustomed to reading three-dimensional schematics so the first step is to redraw it clearly. There are three distinct paths from A to B, colored…
Three… two…one…happy New Year!
As the fond memories of 2014 give way to the exciting possibilities of 2015, many people begin the New Year by making resolutions: some modulate their junk food intake; others filter out a bad habit; a few even integrate…

In my previous blog post , I explained the differences between a SAR ADC’s throughput and response time. Today, let’s see how an interface topology affects the throughput and response time of a SAR…
Many applications, such as motor drives and power inverters, require isolated measurements of both current and voltage. Although optimized for current sensing applications, TI’s isolated delta-sigma modulators enable high-performance voltage measurements…
While working on a low-noise amplifier circuit for an upcoming TI Designs reference design , I was caught off-guard by some interesting behavior. Casually moving the printed circuit board (PCB) on my workbench caused the output voltage to jump! Fascinated…
A few years ago, a customer asked me a rather surprising question: “I realize I am exceeding the maximum supply-voltage rating, but how long will your OPA373 operational amplifier continue to operate if it is powered by a 12V supply?” The operational…

My previous blog Input considerations for SAR ADC's , introduced various input types for Successive Approximation Register (SAR) analog-to-digital converters (ADCs): single-ended, pseudo-differential…
