RMS
1. All electrical values are guaranteed with correlation measurements at 2.4 V and 5 V.
2. Standby mode is active when V
STBY
is tied to GND.
3. Dynamic measurements - 20*log(rms(V
out
)/rms(V
ripple
)). V
ripple
is the superimposed sinus signal to V
CC
@ f = 217 Hz.
4. Independent of Gain configuration (6 or 12 dB) and between IN+ or IN- and GND.
