ADAU1787 current consumption in software power-down when using the internal DVDD LDO
We are characterizing the power consumption of the ADAU1787 in a battery-powered embedded platform. During these tests, we observed a large difference between hardware power-down and software full-chi

Adding some information that is missing from the DSP checksum calculation documentation page
The DSP Wiki page at https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/basicdsp/checksum discusses how to calculate the checksum for a running DSP but some important information was

Checksum error using interface write
Hi everyone, 2 years ago I started a thread with the same problem. Due to my routine, the project became a dust collector haha.... So, now I'm back and spend more 30h trying make this work, without su

Interface write block causing boot failure
Hi everyone, I'm working with a project that need change between 3 inputs, so I'm using a rotary encoder to do this job. The problem it's when I use a Interface Read/write block to save on my EEPROM t

what are the possible options for summing Left and right signal into mono signal ?
hi all, I would like to know what are the different possible ways to mix L & R signal of a stereo audio input flow into a mono signal output. The immediate use case is to derive a mono subwoofer chann

ADAU1761 SNR x Power profile
Hi Folks, ADAU1761 datasheet shows in table 4 the Typical THD + N for each power profile considering that all bias settings (MXBIAS, ADCBIAS, HPBIAS, DACBIAS, RBIAS, PBIAS) are configured for the same

What is the "power-down" state of the ADAU145x?
For standby (soft powerdown) operation we need to of course draw minimal power, and I'd like to avoid switching the IOVDD off, mostly because voltages on the potentially still-active I2C bus can destr

Audio processor recommendation for megaphone project
Hi, We are working on a low-power battery-operated megaphone/bullhorn project (purpose is to amplify a user's voice). In terms of the audio flow, the user's voice will first be captured by 1 - 2 digit

ADAU145x power down
Can we use the START_CORE register to enter a low power state with fast power up? Please advice how to enter power saving mode with fast recovery - with no re-booting? Audio Signal Processors adau1451

multiple stimulus with single probe
I am trying to probe from the merge of 2 different stimulus blocks and looking for some clarification. I click probe labeled 'L Probe', then the Stimulus labeled 'Left Stim' and see the response of ev

ADAU1701 in self-boot mode with reduced power consumption ?
Hi all, i need to know if it is possible to have the ADAU1701 (configured in self-bot mode) while powered down most of all chip sections (for reduced stand-by consumption) and observing an ADC for sma
