    Entertainment systems take up a large chuck of market share in the consumer electronics niche. The entertainment systems largely include audio and video systems. The CODECs are an integral part of any audio electronic system. CODEC is a short form for coder-decoder. The primary task of an audio CODEC is to convert analog audio signals to digital signals and convert back the digital audio signals to analog signals. The ADC (analog to digital converter) and DAC (digital to analog converter) are the essential parts of an audio CODEC. These CODECs are widely used in sound cards, amplifiers, stereo sound systems and studio recording equipment.

    What is SGTL5000XNAA3?

    The SGTL5000XNAA3 is a low power stereo CODEC with integrated headphone amp developed by Freescale Semiconductor. This IC is designed to provide a single chip solution for devices which require LINE_IN, LINE_OUT, MIC_IN, HEADPHONE_OUT, and digital I/Os. The major advantages of SGTL5000XNAA3 are the ultra low power consumption, high performance, and small footprint. The IC is ideal for audio applications such as media players, navigation devices, smart phones, tablets, gym machines and consumer electronics. The cap-less headphone design and internal PLL features keep the device cost reasonably low.
