1. Grounding and Power Supply Decoupling
VDD and VSS are supplied from analog supply and should be separated from system digital supply. Decoupling capacitor,
especially 0.1
μ
F ceramic capacitor for high frequency should be placed as near to VDD as possible. The differential
Voltage between VDD and VSS pins set the analog output range.
2. Analog Outputs
The analog outputs are single-ended and centered around the VCOM voltage. The output signal range is typically 3.40Vpp
(typ@VDD=5V). The phase of the analog outputs can be inverted channel independently by INVL/INVR bits. The
internal switched-capacitor filter and continuous-time filter attenuate the noise generated by the delta-sigma modulator
beyond the audio passband. The output voltage is a positive full scale for 7FFFFFH (@24bit) and a negative full scale for
800000H (@24bit). The ideal output is VCOM voltage for 000000H (@24bit).
DC offsets on analog outputs are eliminated by AC coupling since analog outputs have DC offsets of VCOM + a few mV.
Figure 11 shows an example of the external LPF with 2Vrms output.
