5.5Connection Diagram for Practical Applications

The PCM3793A/94A Daughter Card has been configured to measure dynamic audio performance by common audio analyzer equipment.

In a practical application (such as portable audio player or cellular phone), simple components set up as shown in Figure 5-15will be reasonable to save assembly and test spaces. Specific component values are listed in Table 5-5.
