Can ADAU1701 to use a software flag?
Hello, I want to use flag to indicate some status when I detect something. I can use MP pin for GPIO hardware indication to outside MCU controller. Here is mine 1701 pin setting: Currently, I have 4 G

ADAU1701 duplicate power pins
Hello All, I am currently working on the PCB layout for a board that includes an ADAU1701. However, I am a little confused with the power pins. The chip has a pair of power and ground pins in each cor

ADAU1701 toggle Nth order filters with GPIO
Forgive me if the answer is obvious because this is only my 2nd project in sigmastudio. I want to have selectable Nth order filters using a GPIO. So far I have not used any GPIO in my project. I see t

Reading Duty Cycle from ADAU1466 MP pin
I want to read in a signal to ADAU1466. I have this signal connected to either MP or AUXADC pin through resistor stuff options. The signal has the following four possible options: high low 1kHz square

ADAU1701 AUX controlled "graphic EQ" possible?
Is it possible to design an eq with fix frequency and Q and make the cut/boost variable with an external potentiometer? I want to use the four aux analog inputs to controll some fixed frequencies live

Spikes on MPIO outputs
I designed and built a board using the ADAU1446. I have done several other projects with I2S, but this is my first time with a DSP. The ADAU1446 is connected via I2C to a Raspberry Pi. The DSP respond

ADAU144x MP pin initialization glitch
Greetings! I've been observing the MP pins of the ADAU1445. It seems that no matter what mode they're set to (in a program stored to EEPROM for self-boot), they always pull high for ~100ms when the de

MultiPurpose pin jitter on ADAU144x
I'm finding that I can't get a stable fast (10kHz) square wave out of the MultPurpose pins on my ADAU1445. My scope is telling me it's rock solid 10kHz but I see it scooting around. When I use the pin
