All voltage values are with respect to ground with DGND, AGND1

With CS low the falling R/C edge starts a conversion. If R/C and AGND2 wired together (unless otherwise noted). returns high at a critical point during the conversion, it can create errors.

Full-scale error is the worst-case of –FS or +FS untrimmed clamped by internal diodes. This product can handle input currents of deviation from ideal first and last code transitions, divided by the transition 90mA below ground without latchup.
