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.

Bringing Music to Life on Smartphones and Mobile Devices
These new performance levels for mobile devices makes the highly integrated ES9118 SABRE HiFi SoC the perfect choice for true
audiophile experiences that were previously only available with large, expensive home theater components.
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.
