20 / 39 page  7.3 Feature Description 7.3.1 Gain Control The PGA854 uses three pins to set the amplifier gain. These gain select pins are set with respect to DGND. This configuration simplifies the design when compared to programmable-gain amplifiers requiring a SPI or other digital interface options for gain changes. Figure 7-1 shows the gain-setting block diagram. Table 7-1 lists the gain options. Any gain select pin that is not driven by an external source is automatically biased at DGND using internal pull-down options. Gain Decoder A2 A1 A0 D GND Figure 7-1.
