NOTES

1 Maximum input voltage is 1 V less than VDD.

2 Guaranteed but not production tested.

3 Digital input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.

4 See timing diagram.

5 Measured as the change in the bipolar zero error over temperature. This error does not include the error introduced by the

external reference drift.

6 This error does not include the error introduced by the external reference drift.

7 INL is measured as a 7-bit +sign ADC with 8-bit resolution.

NOTES:

1 Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a

stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.

2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps

(HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short

transients outside the supplies of less than 100mA for less than 100µs.
