Command Register
The MAX9702 has one command register that is used to
set speaker and headphone gain, select an input mode,
and enable/disable shutdown. Table 3 describes the
function of the bits contained in the command register.
Programmable Speaker Gain
The MAX9702 has eight internally set speaker gains
selected by B0–B2 (see Table 4).
Programmable Headphone Gain
The MAX9702 has four headphone gain settings select-
ed by B3 and B4 (see Table 5).
Programmable Input Modes
The MAX9702 features a multiplexer that selects
between the stereo and mono inputs. The mux also
acts as a mixer when the mono and stereo inputs are
enabled at the same time. The MUTE function disables
the input signal to the output. All modes are selected
through B5 and B6 (see Table 6).
The MIX function attenuates and mixes the MONO and
STEREO signals. Each input signal is attenuated by
6dB prior to being mixed. This attenuation preserves
headroom at the output. The output signal is represent-
ed by the following equation when in MIX mode:
where AV is the amplifier gain.
