Note 1:

Offset Error is measured with respect to an ideal first-code transition that occurs at 1/2LSB.

Note 2:

Sample tested at +25°C to ensure compliance.

Note 3:

Accuracy may degrade at conversion times other than those specified.

Note 4:

Power-supply current is measured when MX7575/MX7576 are inactive, i.e.:
For MX7575

CS = RD = BUSY = high;

For MX7576

CS = RD = BUSY = MODE = high.
