Hello,
For the ADG5206, ADG5208, or ADG5408 multiplexer, what is the current consumption when the digital input is around 3V, and not around Vdd?
I need +/-12V as the power supply of the multiplexer.
Vinson
Hello Vinson,
The information regarding your scenario above is not immediately available. We are working to gather this information and will update you when it is available.
Regards,
Sean
The IDD for a ±12V supply will be typically 40uV. For each digital input at 3V, you should add ~5uV. The value for an 16:1 multiplexer (ADG5206) with all digital inputs asserted; A0, A1, A2, A3, EN, selecting Switch 16, ~= 65uV.
Hello Sean,
Are your digital inputs assumed to be around 3V, while Vdd/Vss is +/-12V?
Should it matter what the digital input level are, in relative to Vdd/Vss, and how it affects total current consumption?
Sincerely,
Vinson Go

The digital voltage should be below 0.8V for a valid low input and it should be above 2V for a valid high input.
Relativity to voltage supply is not a concern as these are valid across the supply range.
Thanks.
