Preliminary specication
2
× 1.4 W BTL audio ampliers 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
to
2. The DC output voltage with respect to ground is approximately 0.5VDD.
3. 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).
