μVRMS

1.

All electrical values are guaranteed with correlation measurements at 2.4 V and 5 V.

2.

Standby mode is active when VSTBY is tied to GND.

3.

Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the superimposed sinus signal to VCC @ f = 217 Hz.

4.

Independent of Gain configuration (6 or 12 dB) and between IN+ or IN- and GND.
