Description
DESCRIPTION
The NL120S Audio Amplifier is a power amplifier for driving a 4 or 8 ohm loudspeaker such as the NL985S. It has sufficient power amplification to raise a +20mV signal to a moderate sound level. The NL120S Audio Amplifier module features an input selector for switching between two input signals, and the options of amplifying only positive or negative peaks (useful when baseline noise masks the sounds of nerve spikes of interest). The output is shaped to improve the low frequency response of small loudspeakers, and is power limited to minimise the nuisance caused by large transients such as shock artefacts.
