1.4 W BTL audio amplifiers with digital
volume control and headphone sensing
TDA8552T; TDA8552TS
Notes
1.
With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal
R
L
to
2.
3.
The DC output voltage with respect to ground is approximately 0.5V
DD
.
Output voltage in mute position is measured with an input of 1 V (RMS) in a bandwidth of 20 kHz, so including noise,
gain select pin is LOW (0 V).
