To allow the comparison of different op-amps in a headphone amplifier, [Stephan Martin] has created a stereo amplifier board complete with sockets to take single or dual op-amp chips.

Members can download this article in PDF format. The precision op amp plays a key role in analog and mixed-signal circuits. Applications extend from measuring large currents by amplifying the ...

The stability of high-unity-gain-bandwidth op amps is susceptible to stray capacitances. Instability doesn't first show up as oscillation, but rather pronounced overshoot and ...
