Working Principles

The DMVA4AAAR is an audio amplifier integrated circuit designed to amplify low-level audio signals. It operates by receiving an input audio signal through the non-inverting (IN+) and inverting (IN-) inputs. The internal amplification stage increases the signal level, which is then delivered at the output pin (OUT). The gain can be adjusted using external components connected to the bias voltage input (BIAS) pin.
