Errata: CS5532/34-BS rev D Silicon Errata (Reference CS5532/34-BS data sheet revision DS755F2 dated MAY ’07). Description: The clock generation circuitry (the on-chip oscillator and the comparator that follows it) may fail to generate a reliable clock for the converter under some bipolar power supply conditions. Work Around: To ensure proper operation when using the on-chip gate oscillator with the converter powered from bipolar supplies, the following restriction is to be followed: VD+ must be more positive than +3.2 V and VA- cannot be more negative than -[(VD+)-0.3]. For example: If VD+ = 3.3 V, then VA- cannot be more negative than -[3.3-0.3] or –3.0 V. If the converter is operated from a bipolar supply of: VA+ = VD+ = +3.3V and VA- = -3.3 V or: VA+= VD+ = 3.0 V and VA- = -3.0 V the converter should be driven from an external clock source.
