In applications such as position sensors, data-acquisition systems and resistance temperature detectors (RTDs), it is important to design…

Electronics such as smartphones, tablets, notebooks and wearable products are becoming more multifunctional, smaller and slimmer. Achieving higher functionality in smaller form factors requires extremely…

When responding to questions posted on TI E2E™ Community forums, we frequently run simulations using TINA-TI™ software, a SPICE-based simulation program. Since we are always in the process of updating…

Many sensors produce low-level DC outputs that require a high input-impedance amplification stage to increase the signal amplitude. Sensors used in personal and portable electronics require operational…

In my last blog, I described how a customer had been operating their op amp circuit with a power supply voltage level that was too high for the amplifier and the consequences of doing this. Recently, while…

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 …

When we set out to create an operational amplifier (op amp) for headphone applications (which became the OPA1622 op amp), one of the first questions we needed to address was…

President Ronald Reagan frequently said “trust but verify” when discussing U.S. relations with the Soviet Union. Some say it comes from a Russian proverb, “doveryai no proveryai.”

Trust but…

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 …

In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery…

Photodiode-based light sensing is a common application of operational amplifiers (op amps) used in medical equipment, industrial automation, robotics, point-of-sale machines, drones, smoke detectors and building…

Applications engineers tend to overlook printed circuit board (PCB) layout during circuit design. It is often the case that a circuit’s schematic is correct, but does not work, or perhaps works with reduced performance…

Pop quiz! Take a look at the total harmonic distortion and noise (THD+N) curve in Figure 1. It’s for an OPA1688, a 36V, 10MHz audio operational amplifier (op amp…

In part three of this five-part blog series, we introduced a simple control-loop model for distortion in an operational amplifier (op amp), repeated here in Figure…

This post was co-authored with John Caldwell.

In the final installment of this five-part blog series, I will discuss pop/click noise in operational amplifiers (op amps) driving headphone loads, and some techniques…

“Hey! Turn it down!”

You’ve probably heard these words at some point, especially if you’re like me and enjoy listening to music LOUD! If you decide to oblige and actually “turn it down” then what must you do? Reach for the volume…
