... The device allows independent gain while summing signals from various audio sources. Thus, in cellular handsets, the earpiece, the loudspeaker and even the melody ringer can be driven with a single NCP9004. Due to its low 42 mV noise floor, Aïweighted, a clean listening is guaranteed no matter the load sensitivity. ...

... Detailed Description The basic structure of the NCP9004 is composed of one analog preïamplifier, a pulse width modulator and an Hïbridge CMOS power stage. The first stage is externally configurable with gainïsetting resistor R fixed feedback resistor R (the closedïloop gain is fixed by f the ratios of these resistors) and the other stage is fixed. The load is driven differentially through two output stages ...

... When using an input resistor set to 150 kW, the gain configuration is 2 V/V. In such a case, the input capacitor selection can be from with cutoff frequency values between 1 Hz and 100 Hz. The NCP9004 also includes a built in low pass filtering function. It’s cut off frequency is set to 20 kHz. ...
