The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

The TSV7722 dual op amp from STMicroelectronics provides a gain bandwidth of 22 MHz and is unity-gain stable. With a maximum input-offset voltage of 200 μV (50 μV typical) and low input-voltage noise ...

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 ringing. Op amps such as ...

Speed is an important parameter that engineers must consider when choosing op amps for their designs. Unfortunately, speed does not come free and usually trades off with power consumption; the faster ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...
