The difference between AVC and AGC
Hi, The block "AVC" is used. The curve of this AVC is as follows: it follows the input with a gain of -18dB and saturates at level of 0.538Vcc (crete-to-crete). The 0dBFS level is 1.1Vcc, so here 0.53

Can I use this circuit to use GPIO to control MUX ?
I want to use a GPIO to control a MUX in DSP. My GPIO connects to a hardware switch, when switch to SRC1 , it pulls high , when switch to SRC2, it pulls low. Then , I use this curcuit to control MUX i

I have ADAU1452 schematic that I need to run on an ADAU1451. Do i really need to redraw the whole schematic?
I developed a fairly large algorithm in SigmaStudio, which runs with about 90% instruction / cycles (just to give some indication of it's size). I've been testing / running the code on the EVAL-ADAU14

Interchangeability of ADAU1452/1451/1450 and ADAU1462/1466
Hello, As said in ADAU1462/1466 datasheet, it seems to be compatible pin to pin and in registers to the ADAU1452/1451/1450. I would like to know if this is really true and (with a reduced signal proce

ADAU1463/67 State of I2S Bus in RESET
Hey everyone, quick question about the ADAU1463/67 State of I2S-Bus-Pins in RESET Mode. I suspect the ADAU1463 is behaving similar to the ADAU1451 on the I2S-Pins, therefore the answer ( RE: DSP - ADA

ADAU1451/2/equivalent: Ridiculous leadtimes, preventing adoption
We've been working on a new design that uses the ADAU1451. ADI is showing leadtimes to **2024** now on all of these and equivalents (1452, etc). That's absolutely absurd. Some of the distributors prom
