multi channel anologue

Postby siliconchip » Mon Aug 26, 2019 2:55 pm

hi all,
apology's if this is posted in the wrong section, im aiming to use 3 analogue inputs in turn to read data but want to connect all three to the same output in turn whats the easiest way to connect all three inputs to a single output without interfering with each other,i had thought initially of using diodes but the 0.7v diode drop will interfere with the adc reading

regards bob
