NOTES:

(1) Full Scale Range (FSR) is 10V for unipolar mode.

(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) Specified values guarantee functionality. Refer to other parameters for accuracy.

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.

3 GND refers to AGND and DGND.
