ALC Attack Rate (ARATE[5:0])
Default: 000000
Function:
Sets the rate at which the ALC attenuates the analog input from levels above the maximum setting in the
ALC threshold register.
The limiter attack rate is user-selectable but is also a function of the sampling frequency, Fs, and the SOFTx
& ZCROSSx bit settings unless the disable bit for each function is enabled.
ALC Release Rate (Address 1Dh)
ALC Release Rate (RRATE[5:0])
Default: 111111
Function:
Sets the rate at which the ALC releases the PGA & digital attenuation from levels below the minimum setting
in the ALC threshold register, and returns the input level to the PGA_VOL[4:0] & ADCx_ATT[7:0] setting.
The ALC release rate is user selectable but is also a function of the sampling frequency, Fs, and the SOFTx
& ZCROSS bit settings unless the disable bit for each function is enabled.
