PRODUCTION DATA
As with any analog signals, appropriate printed-circuit-board layout and grounding techniques must be followed to eliminate ground loops, unwanted parasitic effects, and noise.
In addition to grounding, ripple and noise spikes on the power-supply lines due to digital switching or switching power supplies can corrupt the signal. TI recommends a noise-free design using separate analog and digital ground planes with a single-point connection to achieve high accuracy.
