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.
