21 / 148 page ![]() DS880F4 21 CS4207 COMBINED DAC INTERPOLATION & ON-CHIP ANALOG FILTER RESPONSE 9. Measurement Bandwidth is from Stopband to 100 kHz. DC ELECTRICAL CHARACTERISTICS (AGND = 0 V; all voltages with respect to ground.) 10. The DC current draw represents the allowed current draw from the VCOM pin due to typical leakage through electrolytic de-coupling capacitors. 11. Valid with the recommended capacitor values on VBIAS. Increasing the capacitance will also increase the PSRR.
