CONFIDENTIAL ES9219 32-bit Stereo Low Power DAC with Headphone Amplifier, Analog Volume Control, and Output Switch Analog Reinvented s The ES9219 is a high-performance 32-bit, 2-channel audio SABRE HiFi D/A converter with QUAD DAC+ technology, headphone amplifier, analog volume control, dynamic range enhancement (DRE) 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 III DAC architecture and Time Domain Jitter Eliminator, the ES9219 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 ES9219s 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 user presets is included for customizable sound signature. Additionally, the ES9219s 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 ES9219 for lowest power consumption in non-HiFi mode. Residual distortion from suboptimal PCB components and layout can be minimized using ES9219s unique THD compensation circuit, while PCB footprint and bill-of-material are minimized via the ES9219s integrated feedback resistors and low-noise DAC reference LDO. The ES9219 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 42-CSP package.
