... DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.8W) into 4 with less than 10% (1.0%)THD+N. The attenuator range of the volume control in APA2068 is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. The advantage of internal gain setting can be less components and PCB area. Both of the ...

... The gain levels are 2dB/step from 20dB to -40dB in then pulls low the BTL mode, and the last step at -80dB as mute mode. Input Resistance, Ri The gain for each audio input of the APA2068 is set by the internal resistors (Ri and Rf) of volume control amplifier in inverting configuration. SE Gain = ...

... Typical applications employ a 5V regulator with 1.0 F and a 0.1 F bypass capacitor as supply filtering. This does not eliminate the need for bypassing the supply nodes of the APA2068. The selection of bypass capacitors, especially Cbypass, is thus dependent upon desired PSRR requirements, click and pop performance. ...

... F or greater placed near the audio power amplifier is recommended. Optimizing Depop Circuitry (7) Circuitry has been included in the APA2068 to minimize the amount of popping noise at power-up and when coming out of shutdown mode. Popping occurs whenever a voltage step is applied to the speaker. In order to eliminate clicks and pops, all capacitors must be fully discharged before turn-on ...

... Mute Function The APA2068 mutes the amplifier outputs when logic high is applied to the MUTE pin. Applying logic low to the MUTE pin returns the APA2068 to normal operation. Prevent unanticipated mute behavior by connecting the Mute pin to logic high or low. Do not let the Mute pin float. ...
