INTRODUCING THE ES9118 SABRE HIFI SOC Revolutionizing Smartphone Audio Widely recognized as the gold standard in Audio Digital-to-Analog Converter (DAC) technology, ESS Technology has introduced the ES9118 SABRE HiFi SoC to deliver unprecedented audiophile grade experiences to the smartphone market. The ES9118 is the highest performing audio subsystem available for smartphones and other mobile applications. This new class of HiFi System-On-Chip (SoC) integrates ESS’s award-winning DAC technology, headphone amplifier and output switch. It leverages the company’s patented 32-bit HyperStream architecture to deliver up to 126 dB Signal-to-Noise Ratio (SNR) and -113 dB Total Harmonic Distortion plus Noise (THD+N) of audiophile quality sound all the way to the headphones.

With upwards of 67% of people accessing music through their smartphones, and 38% listening through headphones – 43% of consumers say the highest quality sound format is an important factor in making purchasing decisions. Smartphone manufacturers need to address the increasing demand for higher quality audio – exactly the challenge solved by the ES9118 SABRE HiFi SoC. ESS Technology –Bringing Music to Life ES9118 Product Brief Optimized for Smartphones – Comprehensive Format Support The ES9118 supports the industry’s most popular high resolution and lossless audio formats including FLAC, ALAC, AIFF and WAV. It also completely supports compressed legacy formats so the consumer is assured that they will have the best listening experience possible. By integrating SABRE building blocks including the DAC, headphone amplifier, feedback resistors, output switch and low-noise DAC reference into a single package, the ES9118 also reduces the amount of board space used by the audio subsystem enabling ever-shrinking, slimmer phone formats demanded by today’s consumers. Further Technical Specifications The ES9118 SABRE HiFi SoC is a 32-bit, 2-channel audio digital to analog converter integrated with headphone amplifier and output switch designed for audiophile-grade applications in an easy-to-use 40-CSP or 40-QFN package, delivering up to 126 dB SNR and -113 dB THD+N using the ESS patented 32-bit HyperStream® DAC architecture and Time Domain Jitter Eliminator. The ES9118’s integrated DAC supports up to 32-bit 384 kHz PCM and DSD256 data in master or slave timing modes. A fully programmable FIR filter with seven presets provides a customizable sound signature and the ES9118’s integrated headphone amp supports up to 1.1Vrms output with analog volume control to reduce output noise at real-life listening levels. The patented, integrated output switch allows non-HiFi sources, such as speech, to bypass the ES9118 to minimize power consumption. Residual distortion from suboptimal PCB components and layout can be minimized using ES9118’s unique THD compensation circuit, while PCB footprint and bill-of-materials are minimized by the integrated feedback resistors and low-noise DAC reference LDO.
