EVAL-CONTROL BOARD for evaluation/demonstration purposes.
Linearity error refers to the integral linearity error.
P = PLCC; S = PQFP.
L signifies the low power version.
This can be used as a stand-alone evaluation board or in conjunction with the
This board is a complete unit allowing a PC to control and communicate with
all Analog Devices, Inc. evaluation boards ending in the CB designators.

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