The Absolute Maximum Ratings of the AD7172-4 (p. 8) show two specifications for AIN pins: 10 mA and -0.3 V--AVDD+0.3 V.
Can I assume the DAC is safe as long as I ensure one of these conditions is met? For instance, I measure about 100 uA at -0.4 V. Is this still safe in normal operation? Obviously I understand it will not be functional.
Many thanks in advance.
