Team,
We met two confusions from customer and need your advice here:
VDD=5V, VSS=-5V, 1~6 pin all connected to AGND, control AI_SEL signal to control CD4066B switch AGND or VGND, AI_SEL signal is 5V/-5V.
1. How about the leakage current this application will produce? B/C channels are connected to AGND.
2. If IN2 and IN3 will also need to be connected to -5V even if B/C channels are bypassed? If not necessary, will it affect the leakage current? From customer's test result, it seems if they connect IN2/3 to the AGND, it will produce much higher leakage current than connect to -5V.
Thanks.
