Hi all,
I want to operate a circuit using a 3.7V battery. The circuit will contain op-amps, reference ICs and an ADC. How can I stabilize the battery voltage with maximum efficiency so that the reference ICs and ADC will not be effected?
I was considering using the MAX682 charge pump IC which will keep an output voltage of 5V for an input of 2.7V to 5.5V. I was also considering using the MAX868 inverting charge pump IC since I also need negative rail for the op-amps.
My concern is that these are not be best option for a battery operating circuit which needs to have low power consumption.
Are there any other efficient option for this problem?
