APPLICATIONS

• Mobile phones / Tablets / Digital music players / Portable multimedia players

• Consumer and Audiophile USB DAC headphone amplifiers and A/V receivers

• Professional digital audio workstations and mixer consoles

The ES9218P is a high-performance 32-bit, 2-channel audio SABRE HiFi® D/A converter with QUAD DAC™ technology, headphone amplifier,

analog volume control, and output switch designed for audiophile-grade portable power sensitive applications such as digital music players,

consumer applications such as USB DACs and A/V receivers, as well as professional applications such as mixer consoles and digital audio

workstations.

Using critically acclaimed QUAD DAC™ technology, patented 32-bit HyperStream® DAC architecture and Time Domain Jitter Eliminator, the

ES9218P delivers up to 121dB DNR and –114dB THD+N in HiFi mode, a performance level that will satisfy the most demanding audio enthusiasts.

The ES9218P’s integrated SABRE DAC supports up to 32-bit 384kHz PCM and DSD256 audio data via master/slave I2S/DSD interface in

synchronous and asynchronous sampling modes. A user-programmable FIR filter with 8 presets is included for customizable sound signature.

Additionally, the ES9218P’s integrated SABRE Headphone Amp supports up to 2.0Vrms output with analog gain control to reduce output noise

at real-life listening levels. An integrated output switch allows an auxiliary source such as voice to bypass the ES9218P for lowest power

consumption in non-HiFi mode. Residual distortion from suboptimal PCB components and layout can be minimized using ES9218P’s unique THD

compensation circuit, while PCB footprint and bill-of-material are minimized via the ES9218P’s integrated feedback resistors and low-noise DAC

reference LDO.

The ES9218P sets the standard for HD audio performance enabling SABRE HiFi® experience all the way from the DAC to headphones for

today’s most demanding digital-audio applications in an easy-to-use 41-CSP package or 40 pin QFN package.
