Working Principles

PGA2500IDB operates based on the principle of voltage amplification. The input audio signal is received through the non-inverting (IN+) and inverting (IN-) inputs. The gain control bits (GAIN0 and GAIN1) determine the desired amplification level. The amplified signal is then available at the output pin (OUT). The device can be configured to bypass the internal amplification stage by setting the BYPASS control input.
