Analog Reinvented ES9311Q Dual, Ultra-Low Noise Linear Regulator Datasheet The ES9311Q Dual, Ultra-Low Noise Linear Regulator is the industry’s highest-performance, ultra-low noise regulator optimized to supply the reference voltages for ESS’ 32-Bit SABRE DACs and ADCs.

Audio DACs require a very low-noise reference voltage to achieve high dynamic range (DNR).

The ES9311’s output noise is typically under 1µVrms from 100Hz to 100kHz, and less than 1.3µVrms from 10Hz to 100kHz.
