Figure 7. PCM6xx0EVM Input Architecture for Channels 1 and 2
The IN1 and IN2 input architecture allows these two channels to be quickly configured to support any of
the supported operation modes. The IN1P and IN1M pins of the PCM6xx0 can optionally connect to an
onboard microphone for quick evaluation of a microphone in AC- or DC-coupled modes. Jumper
configuration details can be found in
As shown in Figure
These channels support only AC-coupled line inputs by default, however DC-coupled line and Mic inputs
are supported though the removal or replacement of R34-R45.
