Linearity error here refers to integral linearity error.
RQ = QSOP = 0.15” quarter size outline package; RU = TSSOP, CP = LFCSP.
Z = Pb-free part.
This can be used as a standalone evaluation board or in conjunction with the evaluation board controller for evaluation/demonstration purposes.
This evaluation board controller is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in CB designators.
