CONFIDENTIAL ES9218P 32-bit Stereo Low Power DAC with Headphone Amplifier, Analog Volume Control, and Output Switch Analog Reinvented s 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. 2 The ES9218Ps integrated SABRE DAC supports up to 32-bit 384kHz PCM and DSD256 audio data via master/slave I S/DSD interface in synchronous and asynchronous sampling modes. A user-programmable FIR filter with 8 presets is included for customizable sound signature. Additionally, the ES9218Ps 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 ES9218Ps unique THD compensation circuit, while PCB footprint and bill-of-material are minimized via the ES9218Ps 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 todays most demanding digital-audio applications in an easy-to-use 41-CSP package or 40 pin QFN package.
