Standing alone, this integrator circuit will not be stable because the slightest amount of DC offset in the system will cause the output to ramp up or down until it hits the maximum or minimum voltage ...

An integrator that you configure with an op amp is a simple circuit consisting of a resistor, a capacitor, and an op amp, so how can anything go wrong? In Figure 1, when Z F is a capacitor, the closed ...

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. The circuit ...

The solution was to overlay a DC voltage, and use a summing network composed of a series of op-amps to encode position and limit data as voltage. In operation, the circuit is a straightforward DC ...

Late in September, Linear Technology announced single and dual FET-input op amps (LTC6268 and LTC6269 ... which is where readers can find some of the layout advice. The relevant paragraph begins ...
