MAX9773
Selectable Gain
The MAX9773 features four selectable gain settings,
minimizing external component count. Gains of 12dB,
15.6dB, 20dB, and 26dB are set through gain-select
inputs, GAIN1 and GAIN2. GAIN1 and GAIN2 can be
hardwired or digitally controlled. Table 2 shows the
suggested gain settings to attain a maximum output
power from a given peak input voltage and given load
at VDD = 3.3V and THD+N = 10%.
Custom Gain Settings
The MAX9773 can be set up with any gain setting by
adding three external resistors per amplifier. Figure 6
shows the required circuit for setting up custom gain.
Table 3 displays a list of the components to use for sev-
eral gain settings.
