This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω ...

In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

ROHM Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...

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

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono ...

Everyone has a chip-of-shame: it’s the part that you know is suboptimal but you keep using it anyway because it just works well enough. Maybe it’s not what you would put into a design that you’re ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...

Inside the 670 is Goldmund's proprietary Telos amplification, which is a Class A/B circuit designed to deliver wide bandwidth ...

The small low power op amp can save battery and fit in devices while keeping sensor signals accurate for wearables and ...

The TEAC AX-505 may have a footprint no larger than a sheet of A4 paper, but it has the heart of a lion with 115W per channel into 4Ω. The heart of a great audio system is a superb amplifier. The ...

Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. A maximum input offset voltage temperature drift of ...
