Audio codecs (coder/decoders) are a type of audio data converters that encode analog audio as digital signals and decode digital audio back into analog. Audio codecs contain both an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC). Our Audio ADCs offer some of the best SNR and THD specifications in the industry.
Maxim Integrated's innovative digital audio data converter ICs deliver extremely high SNR and low THD+N performance at low supply voltages while providing flexible clocking, broad sampling-rate support and, in select products, integration of our DirectDrive® headphone amplifiers.
Our high-performance, low-power stereo audio codec ICs are designed for portable consumer applications such as smartphones, tablets, portable gaming systems, and portable media devices. Maxim also provides audio codec ICs for wireless voice headsets and other mono voice audio devices.
Many of our audio codec ICs incorporate Maxim's proprietary FlexSound™ audio technology. FlexSound optimizes signal level and frequency response while limiting the maximum distortion and level at the output to prevent speaker damage. The FlexSound audio signal processor provides low-power advanced signal processing, including equalization, dynamic range compression, speaker protection, microphone noise suppression during wideband calls, acoustic echo cancellation, and ambient aware outputs. FlexSound technology improves loudspeaker performance and prevents speaker damage.
