AD7575–SPECIFICATIONS
Temperature ranges are as follows:
Offset error is measured with respect to an ideal first code transition that occurs at 1/2 LSB.
Sample tested at +25 C to ensure compliance.
Accuracy may degrade at conversion times other than those specified.
Power supply current is measured when AD7575 is inactive i.e., when CS = RD = BUSY = logic HIGH.
