NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; 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 latch-up.

NOTES

1Linearity error here refers to integral linearity error.

2SO = SOIC; RM =

µSOIC.

3This can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BOARD for evaluation/demonstration purposes.

4This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators.
