Single Level Detector in ADAU1452
Hi, I use Single Level Detector to read level in my program. I find that the data from 1452 is 4 bytes which doesn't contain the sign bit, so I think it's not 8.24 format. I have the following questio

ADM811TARTZ WHITH POWER FAIL
ADM811TARTZ is perfect as Logic Low RESET for ADAU1701 and I use it in different hardware. I have to modify a hardware with on board ADAU1701 and I need an IC identical to ADM811TARTZ but with integra

Adau1701 noise (tone) issues
Hi, I have made several prototype boards with the Adau1701 with external ADC/DAC solution (loudspeaker X-over). 1 thing that keeps giving issues, is (too much) noise and more specific a single tone (1

EVAL-ADAU1452MINIZ load from microcontroller
I'm having trouble loading the DSP on a EVAL-ADAU1452MINIZ board using our microcontroller. The code is stable and ported from our ADAU1701 target hardware, with the changes required for the ADAU1452.

ADAU1701: external frequency change detector
In my design (ADAU1701 self-booting) I have a switch that selects sample rate by changing an external oscillator's frequency. I need to generate a reset when that switch changes so that -1701 can load

Using the ADAU1700/1701 DSP for Radio Communications
We are currently working on a multimode radio transceiver and one of the functions we wanted to add was DSP primarily for audio signal processing on SSB receive. This in reality is a low intensity app

ADAU1761 MIC input single Ended Or Differential?
I am confused a bit about the inputs to the PGA. (Figure 33. Stereo Differential Microphone Configuration) ADAU1761 pdf, shows one side of the MIC grounded at the input of the circuit. Seems that just

Low group delay ADC and SigmaDSP?
For my application involving a control loop, I need an ADC with low group delay or conversion time (<10µs) to ensure stability. Unless I missed something, there is no such ADC on any of the SigmaDSP a

Controlling two SigmaDSPs ADAU1701 with one microcontroller
Hi everyone, i want to make that a microcontroller PIC controls two DSPs ADAU1701 at the same time. The PIC has to load the same signal-flow into the two DSPs but the DSPs may have different settable
