an amplifier provides power gain at some combination of voltage and current, and usually into a resistive load. In contrast, an op-amp is configured to increase voltage while delivering up to a specified maximum current to the load. Further, the op-amp can be configured for fixed or adjustab...

(I have already tried adding a dummy load to the power supply hoping that more current draw would cause the output to fall fast enough, but there is still a significant ramp down period). Is there anything else that I can do to stop the op-amps behaving like this?
CIRCUIT INSIGHTYou can view Q1’s base current by adding IB(Q1) to the plot window. How much base current is required during the 1A draw of the load? The op amp supplies this current to the transistor. However, many op amps can only deliver about 10mA! If Q1 is asking for more, ...
Quiescent current draw: 3.5 mA (each channel) Dimensions (L x W x H): 10 x 10 x 5 mm After the first generation, the designer redesigned the Oracle II dual op amp. The bottom area is similar to that of the dual op amp. The pins are familiar and fully compatible with OPA2604AP...
(negligible) current is going into the amplifier and also because I have a source impedance between 1k and 5k for the sensor, so I don't want that to have an adverse effect on the voltage inputs to the amplifier. One op-amp I was looking at was the THS4531 (http://www.ti.com/...
Reconnect the power supplies and observe the current draw to be sure there are no accidental shorts. Now adjust the waveform generator to a 500 Hz sine wave set to a 2.1 V min value and a 2.9 V max value (0.8 V p-p centered on 2.5 V) and again display both the input and output ...
