I want to have minimal power consumption because I will be using waveform purely for visual information, I do not need to send signal further to speaker or headphones
OP specifically states there will be no headphones connected to op amp . Only connection will be the oscope
If I use OPAMP to read cheapo condenser microphone on one end and generate boosted waveform on other end so I can see it with oscilloscope, what would be the power consumption in this case?
The LT1215 is my op amp of choice and the datasheet says IS (supply current) is about 5 mA/per amplifier
(chip is a DUAL AMP package) so total current is 10 mA/per chip.
