ADAU145x generating a reset signal for max hold when reading for example IPAT registers
Hello all, Does anyone know if it is possible to generate a reset signal for a "max and hold" block when reading from, for example, an IPAT register? I have five digital signals on MP inputs, which ca

ADAU1452 Directly Read Held Value in Value Hold Block
On the ADAU1452 I am using 20 instances of the Value Hold block and want my microcontroller to be able to read the held values. I was using the Indirect Parameter Access Table to accomplish this, howe

Can Interface Read/Write store ADC readings or only GPIO state?
Hi, I'm using the ADAU1701. I know how to use Interface Read/Write to save/restore the state of the GPIO inputs after powering the ADAU1701 off and back on. I also think I know how to use Value Hold t

How is hold implemented in peak compressors?
Using the peak compressor, if I turn off the decay time (instant change to unity gain), and then choose specific values of hold in ms, I get big glitches in the output. If I choose other values, I don

How to extract maximum value from "Max and Hold" for calculation?
Hello, I'm using 'Max and Hold' to find the maximum value of the signal between two zero crossings and that works. Now I need to use that maximum value to scale another signal accordingly. The other s

Help on "Max", "Max and Hold", "Max Abs" and "Max Abs and Hold"
Hello, Can't find anything on these in help file. How they differ, how they work? There are other algorithms also without help. Considering that Analog was able to put the whole platform and tools tog

Peak compressor operation noise
Hello everyone, I just tried the peak compressor block on the ADAU1701 evaluation board and noticed it is very noisy when operating on signals with smooth, long envelopes... Be it a sine wave or a sus
