PRODUCTION DATA
CAPA and CAPD are the output voltages of the internal analog and digital voltage regulators. The regulators reduce the supply voltage to operate internal sub-circuits at reduced power consumption. These regulators are not designed to drive external loads. CAPA is the analog regulator voltage output and is powered from AVDD2. The output voltage is 1.6V with respect to AVSS. Bypass CAPA with a 1µF capacitor to AVSS.
CAPD is the digital regulator voltage output, powered from IOVDD. The regulator output is 1.35V with respect to DGND. Bypass CAPD with a 1µF capacitor to DGND.
