Verifying ADAU1701 input and output levels?
Hi all, I've been using the ADAU1701 chip in a speaker project and for the most part things are working as expected however the audio seems to get attenuated on the output ( only able to confirm this

ADAU1701 audio ADC DC offset
Hi ! We are using both audio ADCs of the adau1701. The DSP program is a simple mux allowing us to use either the analog or serial inputs of the DSP (see picture). We are using DIG0 and DIG1 to send bo

DC offset in ADC - minimize/characterize? (ADAU1701)
I noticed a nontrivial DC offset present in the audio ADC that's causing some problems, particularly when low inputs are present (say, 100mVpp) from the customer device, and a fair bit of gain is appl

Input cap values on ADAU1701
Dear All, Can someone explain the function of the input capacitors on the ADC inputs for the ADAU1701. I'm new to electronics and I'm struggling to get hold of any 47uF capacitors at a reasonable pric

What is the Adjustable Low Pass Filter "Step" mean?
Hello guys, Can someone help me to understand what is the " Adjustable LPF " function block which has one parameter call "step", what is this actually work at? I am using ADC to adjust the Low pass fr

Linearity in the regulation of the output level ADAU1701
Hello everyone, In any laboratory, including mine, there is a Low Frequency Function Generator. I needed a second generator to do some tests with 4 fixed frequencies and variable output level control,

Send an address with I2C according to a specific voltage value applied to an ADAU 1701 DAC
I have to read 5 different voltage values on ADC3 of DAU1701. I thought I would use a VCO as an attached figure and then convert the frequency into a specific address corresponding to each single freq
