I will use bridge circuit as might be I have to place dummy gauge for temperature compensation.
One problem: I have placed filter R6,R7,C1,c2 & C3 for filter. Since my circuit is battery powered so what I will do is pass current , take reading & then disconnect the current.
1. In this case, curent is on for very short time & filter capacitors also have to get charged to voltage produce. will it be a problem.
2. I have to use internal IDAC. Setting in register "MUX1", can I use "VREFCON1:0 = 11", so that current consumption can be reduced.
