How to isolate the bandgap output from the nodes which need bandgap voltage in adc? Directly connect, output of bandgap will degrade.
Your help is my hope. Thx!
For example, a 2v voltage had been supplied through bandgap, 1.8v, 1.6v, 1.4v and 1.2v reference voltages are requirested, from 2v node to gnd 5 resistors are serial, then from 4 node four reference voltages are generated, so 4 buffers need to be connected to the 4 node respectively befor they supply outside circuit, right? Thx!
