HARDWARE SETUP This section provides an overview of the evaluation module hardware for setup purposes. Complete schematics at the end of the data sheet are provided. The DATA OUT header is used to connect to the DATA IN header of another PGA2310-EVM when using a daisy-chain configuration. Daisy-chain operation is discussed in more detail under “Dual DUT (or Daisy-Chain) Operation”.

PROGRAMMING THE PGA2310 THE DUT PANEL All controls for the PGA2310 are contained within the DUT panel (see Figure 2). This section describes the functions contained within this panel. GAIN CONTROLS The Gain Controls occupy the bottom half of the DUT panel. There are three gain sliders for the PGA2310, one each for left and right channel, and a Gang slider for controlling both left and right channels simultaneously. When the PGA2310 first powers up, it will reset to maximum attenuation (or mute).

Using the supplied software, two PGA2310-EVM modules may be connected together using the Dual DUT option in the Main panel, as shown in Figure 4. Selecting the Dual DUT radio button will enable the DUT1 and DUT2 control panels. The DUT1 panel was shown previously in Figure 2, while the DUT2 panel is shown in Figure 5. Simply set the controls as previously discussed in the section, “Programming the PGA2310: The DUT Panel” for each device using the appropriate panel.
