TERMINOLOGY

MICN input only in single ended microphone configuration. Maximum input signal to MICP without distortion is -3dBV.

Hold Time is the length of time between a signal detected being too quiet and beginning to ramp up the gain. It does

not apply to ramping down the gain when the signal is too loud, which happens without a delay.

Ramp-up and Ramp-Down times are defined as the time it takes the PGA to change its gain by 6dB.

All hold, ramp-up and ramp-down times scale proportionally with MCLK

Signal-to-noise ratio (dB) – SNR is a measure of the difference in level between the full scale output and the output with

no signal applied. (No Auto-zero or Automute function is employed in achieving these results).

THD (dB) – THD is a ratio, of the rms values, of Noise Signal.

The maximum output voltage can be limited by the speaker power supply. If MONOBOOST=1 then SPKVDD should

be 1.5xAVDD or higher to prevent clipping taking place in the output stage.
