Figure 17. Connection example for 300mW output using BEEPL and BEEPR pins
Note)
1.
MOUT2 output is recommended to be AC coupled to avoid amplified DC offset of common voltage of MOUT2 and
BEEP-Amp is output via BTL Speaker-Amp (that means stand-by current is increased). Capacitor size affects the
cut-off frequency of 1
st
order LPF made by this AC coupling capacitor and series resister in front of BEEP input.
Internal feedback resister of BEEP-Amp which determines BEEP-Amp gain has 30% sample variation.
2.
n
MONO OUTPUT (MOUT2 pin)
The mixed Lch/Rch signal of DAC is output from the MOUT2 pin. When the MOUT2 bit is “0”, this output is OFF and the
MOUT2 pin is forced to VCOM voltage. The load impedance is 10k
(min.). When the PMSPK bit is “0”, the
Speaker-amp enters power-down-mode and the output is placed in a Hi-Z state.
n
MONO LINE OUTPUT (MOUT+ and MOUT- pins)
The mixed Lch/Rch signal of DAC is output from the MOUT+ and MOUT- pins, creating a differential output. Either the
MOUT+ or MOUT- pins can be also used as single-ended output.
