12.2 Monitoring the Signal Path

The PGA450-Q1 has two useful test modes that allow users to quickly observe the echo signal as an

amplified analog signal or from a DAC output which converts a digitally filtered echo signal. In the

Evaluation tab, quick-access buttons Amplifier Output (unfiltered) and Datapath Output (filtered) are

available. The signal is viewable on the DACO pin. Only one mode can be selected at a time. See

Figure 11 and Figure 12 for the captured waveforms.
