Thanks to the promotion of vivo, Xiaomi, Meizu and other manufacturers, the famous audio chip manufacturer ESS Technology is known to everyone. In MWC2016, it also brought the ES9118 specially designed for mobile phones.

Unlike the well-known DAC such as ES9018K2M and ES9028Q2M and the operational amplifier chips such as ES9601 and ES9603, ES9118 belongs to "HiFi System On Chip", that is, HiFi SoC. The mobile SoC we often contact usually represents a collection of CPU, GPU, baseband and other parts, while HiFi SoC is composed of DAC, operational amplifier and output switching. Only one chip is needed to realize the functions of several previous chips, especially suitable for mobile phones. It is a good audio solution.

ES9118 signal noise ratio is 126dB, total harmonic distortion plus noise is -113dB, DAC supports 32 Bit, dual channels, 32 bit 384kHz PCM and DSD256 decoding. Performance is the top level in the audio solution of mobile phones. The appearance of HiFi SoC gives a new mode and direction to the independent audio module of mobile phones. The use of such chips can further save space on the motherboard and reduce power consumption, which is undoubtedly very beneficial for mobile phones with "money for money".
