1. All electrical values are guaranteed with correlation measurements at 2.4V and 5V.
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 = 217Hz.
4. Independent of Gain configuration (6 or 12dB) and between IN+ or IN- and GND.
