I'm trying to power a home-made load cell transmitter using a 24V single SMPS. I need to make +12, 0 and -12 Volts that are capable of 50mA. I wish to power multiple channels of opamps and bridges.
I don't have much budget and availability of components in India.
I have an idea to use 1 LM7812 an 1 LM7912(negative) linear voltage regulators and a voltage divider setup to do this as per the circuit below.
Would this work? I've modified it from the suggestions and articles elsewhere.
Somebody suggested me one other circuit but I am concerned about the current capabilities of the opamp.
Would this work? If yes, please suggest suitable op-amp.
Are there any other techniques that would do the job economically?
