Hi there
we are using OPA1632 to convert single-ended signal to differential signals.Below is sch. note V_input is applied to Vin- pin.of hte amp..
By TI app. note SLOA054, 
, page10, we know from equations (11)-(15),
Vod = Vid = 0 - V_input.
Vout+ = 1.3 + 0.5*Vid =1.3 - 0.5*V_input.
Vout- = 1.3 - 0.5*Vid =1.3 + 0.5*V_input.
For some reason I need to connect V_input to Vin+(pin.8) and connect AGND to Vin-(pin1), I think the red-marked +/- signs in above equations will be opposited. Right?
Vod = Vid = + V_input.
Vout+ = 1.3 + 0.5*Vid =1.3 + 0.5*V_input.
Vout- = 1.3 - 0.5*Vid =1.3 - 0.5*V_input.
Besides of this difference, is there any other influence on circuits performance if I do so? Thanks!
