... 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 NCP2820. Due to its low 42 mV noise floor, A−weighted, a clean listening is guaranteed no matter the load sensitivity. ...

... POWER SUPPLY (V) Figure 33. Turn on Time Detailed Description The basic structure of the NCP2820 is composed of one analog pre−amplifier, a pulse width modulator and an H−bridge CMOS power stage. The first stage is externally configurable with gain−setting resistor R fixed feedback resistor R (the closed−loop gain is fixed by f the ratios of these resistors) and the other stage is fixed ...

... 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 NCP2820 also includes a built in low pass filtering function. It’s cut off frequency is set to 20 kHz. ...
