The ESS ES9033Q Sabre DAC allows audio system designers to save on the total bill-of-materials (BOM), board space and power consumption by taking advantage of the built-in phase lock loop (PLL), eliminating the need for an external crystal or oscillator. Also, the built-in 2Vrms, ground-centered line drivers eliminate the need for external amplifiers required by other DACs.
And the ES9033Q can function at high input sample rates, handling PCM sampling rates up to 768kHz and DSD rates up to DSD512, as well as TDM and DoP formats. It supports all the most popular high-resolution and lossless audio formats including MQA, FLAC, ALAC, AIFF and WAV, as well as compressed legacy formats.
The ES9033Q can be programmed using various input methods, as I2C, SPI, and hardware modes are available. According to ESS Technology, outstanding acoustical performance is achieved with the use of 8 pre-programmed upsampling filters that are designed to preserve the time-domain response while providing the best imaging and accurate signal preservation possible. A stereo de-emphasis filter can also be set if required.
The ES9033Q also has ESS' proprietary HyperStream II modulator that gives ESS' Sabre DACs their legendary sound quality. HyperStream II modulation allows for timing jitter to be pushed out of the audio range so the resulting soundstage is pure and consistent.
The new ES9033Q can be used in receivers, stereo and multichannel setups, with applications for multiple types of audio systems, including professional audio equipment, high end audio components, active speakers, media streamers, gaming motherboards, musical samplers, and audio processors.
The ES9033Q is available in a 28-pin QFN package to minimize the board space. Full evaluation board and reference design are also available.
