Output voltage noise

F = 20Hz to 20kHz, A-Weighted,

Gain = 3.5dB

Filterless, 3D effect off, RL = 4Ω

Filterless, 3D effect on, RL = 4Ω

With LC output filter, 3D effect off, RL = 4Ω

With LC output filter, 3D effect on, RL = 4Ω

Filterless, 3D effect off, RL = 8Ω

Filterless, 3D effect on, RL = 8Ω

With LC output filter, 3D effect off, RL = 8Ω

With LC output filter, 3D effect on, RL = 8Ω

μVRMS

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

with fixed Cin cap (input decoupling capacitor).

See Section 4.6: Wakeup (tWU) and shutdown (tSTBY) times on page 26.

Table 9.

VCC = +3.6V, GND = 0V, Tamb = 25°C (unless otherwise specified) (continued)
