Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

The increasing acceptance of Class D amplifiers has helped them gain market share from their linear Class AB brethren. That acceptance is no surprise; the advantages of Class D amplifiers are legion, ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Using a multi-shunt-based current-monitoring circuit with a 50-MHz op amp delivers an overcurrent detection response time of ...

Quantum computing, an approach to deriving information that leverages quantum mechanical effects, relies on qubits, quantum ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

We talk to engineer Taresh Vadgama, who has spent over 40 years with NAD, and take a deep dive into the legendary budget ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is ...

Inside the 670 is Goldmund's proprietary Telos amplification, which is a Class A/B circuit designed to deliver wide bandwidth and ultra-low distortion. Goldmund says it ensures "pure, uncompromised ...
