NOTES

1Stresses above those listed under “Absolute Maximum Ratings” may cause

permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those listed in the

operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect device reliability.

2Transient currents of up to 100 mA will not cause SCR latchup.

NOTES

1Linearity error refers to the integral linearity error.

2P = PLCC; S = PQFP.

3L signifies the low power version.

4This can be used as a stand-alone evaluation board or in conjunction with the

EVAL-CONTROL BOARD for evaluation/demonstration purposes.

5This board is a complete unit allowing a PC to control and communicate with

all Analog Devices, Inc. evaluation boards ending in the CB designators.
