Op Amp Input Overvoltage Protection:

High precision op amps enable system designers to create circuits that condition signals (amplify, filter, and buffer) while maintaining the precision of the original signal. When information is contained in very small variations of the signal, it is critical that op amps in the signal path perform their operation while contributing very little DC and AC error. The precision of the total system depends on maintaining the precision of the signal path.

New in the Electronics Design Library is Volume 2 of FOCUS ON: Bob Pease on Analog. With very few exceptions Bob Pease is remembered fondly all over the globe for his analog design expertise as well as his sense of humor. Our esteemed competitors Electronics Design (magazine) shared and spread his wit and knowledge with the electronics community for years with his special column “Pease Porridge.”

When choosing an operational amplifier for an application you already know you will be looking at criteria such as supply rail, slew rate, drift, output voltage swing, gain bandwidth, residual current, noise, etc., your final choice will often be a compromise. It goes without saying we will only be considering small signals so when the application calls for high output voltage and current drive something special is required...

2 sided FR4 PCB that implements a configurable op-amp circuit for single SOT23-5 amplifiers and 0805 passive components and 0.1inch grid pins.

STMicroelectronics has introduced two rugged 36-V opamps for automotive and industrial applications. The opamps feature a wide supply voltage range, high stability under difficult operating conditions, and ESD tolerance up to 4 kV.

New old stock (NOS) component supplies can be interesting if you are looking for cheap or obsolete components, but since such parts are old by definition and may have been stocked under less than ideal conditions, it is more than highly recommended to test them before usage. There is nothing worse than debugging a circuit only to discover that the problem is due to the “new” part you just inserted.

Texas Instruments has launched a new audio opamp claimed to be the new standard for high-end audio. The OPA 1622 is the newest member of the popular Burr Brown audio family, which TI took over in 2000. It is the successor to the well-known and renowned OPA 1612.

Elektor is excited to bring you the new Analog System Lab Kit PRO from Texas Instruments! This cost efficient platform is specifically designed for engineering students and enthusiasts to perform analog lab experiments. When using the ASLK PRO you can create almost any analog system using general purpose ICs, such as opamps and analog multipliers. If you want to begin your exploration of the fascinating field of analog system design, this instructive ASLK PRO kit is for you!

Operational amplifiers, or opamps, also written as op-amp and op amp, play an important role in modern electronics circuits. The Op Amp Applications Handbook is probably the most complete opamp reference book available to date. If you want to know everything about operational amplifiers, this 896-page book should definitely be part of your collection. The Op Amp Applications Handbook is now available in the Elektor Store.

Here is an all-analog, all-through-hole, cheap & cheerful preamplifier for that perennial problem of getting the microphone amplification just right, which is a challenge not only with the faithful reproduction of lead vocals during concerts and recordings, but also with campfire and karaoke-ish performances specially when the beer takes hold.
