Ordering Information

17) If the charge pump is engaged, how do I ensure that the converter and its

external components are intrinsically safe?

A: Intrinsic safety prohibits the use of electrolytic (or bipolar) capacitors

thus limiting the use of certain size capacitors. Although a 10 µF cap. is

recommended for the charge pump, two 0.47 µF ceramic caps in parallel

can be used.

18) What benefit does an evaluation board offer?

A: The CDB5525/26 evaluation board saves time and money over prototyp-

ing. The preassembled board comes equipped with an 80C51 microcon-

troller and a 9-pin cable to link the evaluation board to a PC-compatible

computer. The evaluation system also includes software which provides

easy access to the internal registers of the converter and displays the con-

verter’s time domain, frequency domain and noise histogram performance.
