External Analog Back-End Circuit (fs = 44.1 kHz)
For specified performance, the output should be taken between VCOM and AOUTR (or AOUTL). At pins
AOUTR and AOUTL the output is an inverted analog representation of the digital input signal. It is advisable
to add a low-pass filter to the output of the TLC320AD77C to eliminate high frequency noise >80 kHz. See
Figure 5–2 for the recommended analog back-end circuit. The output of this circuit provides the user with
a noninverted signal.
