Genius 14090 points
Part Number: TMUX1204
Other Parts Discussed in Thread: OPA2990, , TMUX1208

Tool/software:

Hello 

Customer plans to use TMUX1204 (x 2pcs) to do the Gain setting of the OPA2990 in Resolver application as below circuitry. Is there any side effect or any need to pay attention? Please help to check on this circuitry!

Application: Resolver for AC inverter

Resolver IC: AS12S1210

R2 Value is 8.5K to 31K Ohm. TMUX1204's Rds,on is about 4.9Ohm. there should have no impact on Gain value settings. 

Regards

Brian

    Hello Brian,

    The diagram looks good. Gain switching is a common application for multiplexers, as long as they are implementing the TMUX1208 within datasheet specification there shouldn't be and issues or concerns. 

    Thanks,
