DC ELECTRICAL CHARACTERISTICS
(AGND = 0 V; all voltages with respect to ground.)
22. The DC current draw represents the allowed current draw from the VQ pin due to typical leakage
through electrolytic de-coupling capacitors.
23. Valid with the recommended capacitor values on DAC_FILT+, ADC_FILT+ and VQ. Increasing the ca-
pacitance will also increase the PSRR.
DIGITAL INTERFACE SPECIFICATIONS & CHARACTERISTICS
24. See “Digital I/O Pin Characteristics” on page 9 for serial and control port power rails.
