† Notice: Stresses above those listed under “Absolute

Maximum Ratings” may cause permanent damage to

the device. These are stress ratings only and functional

operation of the device at these or any other conditions

above those indicated in the operation sections of the

specifications is not implied. Exposure to Absolute

Maximum Rating conditions for extended periods may

affect device reliability.

Note

Accuracy – The accuracy of the meter at full scale is the accuracy of the setting of the reference voltage. Zero is

recalculated during each conversion cycle. The meaningful specification is linearity. In other words, the deviation from

correct reading for all inputs other than positive full scale and zero is defined as the linearity specification.

The LSD stability for 200 mV scale is defined as the range that the LSD will occupy 95% of the time.

Pin numbers refer to 24-pin PDIP.
