APPLICATION INFORMATION
CONNECTION DIAGRAMS
A basic connection diagram is shown in Figure 28, with the necessary power supply bypassing and decoupling
components. TI recommends using the component values shown in Figure 28 for all designs.
The use of series resistors (22
to 100
) is recommended for the SCK, LRCK, BCK, and DATA inputs. The
series resistor combines with the stray PCB and device input capacitance to form a low-pass filter, which
reduces high-frequency noise emissions and helps to dampen glitches and ringing present on clock and data
lines.
