ampop with reference input
Hi,
I need a "voltage reference" build using 1N825-6,2V zener(with 7,5mA current) and an Operational Amplifier LM358 (LM725 has an output current max of 5mA and LM385 is rated 25mA). Output voltage as close as possible to 12V. Inform formula and schematic for future modifications.
Input voltage min. 16V max. 26V.
P.S. As low as possible voltage drift with temperature variations better.
Regards,
Fernnado
