USING THE EVALUATION BOARD
POWER
INPUTS AND OUTPUTS
Power can be supplied to the EVAL-ADAU1777Z in one of three
ways. When Jumper J3 is in the USB/EXT position, power can be
supplied by connecting the EVAL-ADUSB2EBZ (USBi) board
to J1 (see Figure 30) or by connecting a 3.8 V dc to 5.5 V dc
power supply to J2 (tip positive).
The EVAL-ADAU1777Z has multiple audio input and output
options, including digital and analog. There are four singleended analog inputs that are configurable as microphone or line
inputs, dual stereo digital microphone inputs, and two
differential outputs that can also be used in a single-ended
configuration.
Analog Microphone Inputs
For microphone signals, the ADAU1777 analog inputs can be
configured as single-ended inputs with optional programmable
gain amplifier (PGA) mode.
Microphone Bias
15054-030
15054-032
To add MBIAS0 to AIN0, connect a jumper to the J11 header.
Similarly, MBIAS1 or MBIAS0 can be added to AIN1 by
connecting a jumper to the J14 header (see Figure 32).
Figure 32. Microphone Bias Headers
Enable the microphone bias circuitry in the PGA/ADC tab of
SigmaStudio. The appropriate gain settings can also be chosen
via this tab (see Figure 33).
Figure 30. Header J1, Control Port
15054-033
To supply power via a 1.5 V battery, J3 must be set to the BATT
position, and the battery must be connected to J5. The onboard regulator generates the 3.3 V dc or 1.8 V dc supply,
determined by S1, for the on-board circuitry. LED D1 lights up
when power is supplied to the board. To connect power to the
ADAU1777, connect the J8, J10, J12, and J17 jumpers (see
Figure 31).
