DESCRIPTION
Bass ALC (Automatic Level Control) function can be adjusted by a dedicated pin. Figure 2. Block Diagram The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained. 5.6K 3.3nF 68nF 68nF 0.47µF IN1-R 25K MUX_R TREBLE-R BASSI-R BASSO-R gm +6dB ÷ 0dB VOLUME TREBLE RB 16Ω or 32Ω BASS x1 220µF PGND-R PVS-R OUT-R 25K 0.47µF IN2-R 25K +6dB ÷ -63dB SUPPLY BASS_ALC CONTROL 25K 0.47µF ALC HALF_WAVE RECTIFIER I2C BUS DECODER + LATCHES SCL SDA IN1-L 0.47µF 25K +6dB ÷ -63dB x1 VOLUME 25K +6dB ÷ 0dB gm TREBLE BASS 16Ω or 32Ω RB VRE...
