ADAU1452 Slave Microcontroller port & USBi
Using a Teensy 4.1 to control ADAU1452, so the tutorial written for the Teensy 4.0 is really helpful, thanks. My workflow is to develop and test the Sigma Studio design and use a USBi interface to loa

Wondom DSP Kernel Board APM 2 - Power Supply ?
Hello, have a maybe stupid question concerning a power supply for the APM 2 Board. Reason, I have connected a 5 Volts power supply to the APM 2 and the unit "smoked off", means, it got hot and now if

Sequencing separate regulators for AVDD and IOVDD for ADAU1761
I plan to use two ADP7104 (3.3V) regulators to power the AVDD and IOVDD separately on an ADAU1761, is this possible? If yes are there any restrictions on power sequencing, e.g IOVDD has to come up fir

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

ADAU1466 operating current and clock speed variation
Hello, and thanks in advance to the AD engineers who hopefully look at this! I would like to use the ADAU1466 in an upcoming design, but have a question about power consumption since my application is

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

EVAL_ADAU1701MINIBZ with NO power supply?
Hi, I'm writting here to announce that I have just recived an EVAL_ADAU1701MINIBZ evaluation board, which in theory comes with the USBi board, the ADAU1701 board, the USB cables and a POWER SUPPLY. "T

Power supplies, capacitors, and application schematics
In SigmaDSP datasheets, the pin description table often has a statement like the following: This pin should be decoupled to DGND with a 100nF capacitor. However, if you look at the application circuit

About the relation between AVDD and IOVDD at ADAU1761
Should I use same voltage for AVDD and IOVDD? [ex) AVDD = IOVDD = 1.8 or 3.3V] If power supply settings are AVDD = 3.3V and IOVDD =1.8V, is it OK? And in this case,is the supply current increase? My c
