Note 10:
Recommended operating conditions.
Note 2:
All voltage values are with respect to ground with DGND, AGND1
Note 11:
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 small
Note 3:
When these pin voltages are taken below ground or above VANA = errors. For best results ensure that R/C returns high within 1.2µs after the VDIG = VDD, they will be clamped by internal diodes. This product can start of the conversion. handle input currents of greater than 100mA below ground or above VDD

As measured with fixed 1% resistors shown in Figures 3a and without latch-up. 3b. Adjustable to zero with external potentiometer.
Note 4:
When these pin voltages are taken below ground, they will be

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. These pins are not clamped to VDD. voltage (not divided by the full-scale range) and includes the effect of
