Overview

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.

Key Features

  • not available in commodity regulators: the two outputs require no decoupling capacitors, remote load sensing ensures output voltage accuracy right at the load, there are two output enable inputs, the outputs have a soft-start function, plus power-good, over-temperature warning, and over-temperature shutdown outputs. The ES9311Q Dual, Ultra-Low Noise Linear Regulator is available in a 30-pin, 3mm x 5mm QFN package.
