I have a 40dB active bandpass filter being powered off a single rail power supply with the TL2426 providing a virtual ground so I can get a dual power supply configuration. Currently, I'm having issues understanding the concept of current sink and current source in this configuration.
When connected to a dual rail power supply, the active bandpass filter draws 60mA. Now according to the datasheet, the TL2426 can source 20mA. Does this mean this is the maximum output current that the TL2426 can provide to the circuit
In the configuration shown above, the whole circuit draws ~71mA and the amplifying circuit still works as expected which I found suprsing, I've not probed the rails to check how balanced they are but unless I've misunderstood the concept of sourcing and sinking, if the circuit requests 60mA and the TL2426 can only give 20mA, shouldn't the circuit not just work?
