NOTES
1
Linearity error refers to the integral linearity error.
2
Q = Cerdip; R = SOIC; RS = SSOP.
3
L signifies the low power version.
4
This can be used as a stand-alone evaluation board or in conjunction with the EVAL-CONTROL BOARD for
evaluation/demonstration purposes.
5
This board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards
ending in the CB designator. For more information on Analog Devices products and evaluation boards visit our

NOTES
1
Stresses 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.
2
Transient currents of up to 100 mA will not cause SCR latchup.
