ES9312 Datasheet Dual Ultra Low Noise Regulator

Manufacturer: ESS Technology

Overview: Analog Reinvented ES9312 Dual Ultra Low Noise Regulator Product Datasheet The ES9312 is a 2nd generation dual ultra low noise linear regulator optimized to supply the reference voltages for ESS Technology’s SABRE® products as well as maximize all DAC and ADC performance. Each regulator’s output noise, as low as 1µVrms from 10Hz to 100kHz, allows for the highest achievable dynamic range and lowest noise performance making it the ideal low noise regulator for use with all ESS SABRE® DACs and ADCs as well as general very low noise voltage requirements.

General Description

Ultra low noise regulated to 180mA per output at Excellent line and load regulation for output current to maintain peak multiple voltage levels performance 1µVrms output noise (10Hz to 100kHz) Over-current, under-voltage, over-temperature warning and protection Calibration mode for Sabre DACs Internal voltage fixed mode presets External fixed mode Excellent performance to maintain highest DNR and THD+N measurements Protection for regulator and device against system issues Allows adjustment of output voltage to ensure output levels are maintained in selected ESS DACs such as the ES9069, ES9039Q2M and others Fixed mode allows for simple pin configuration for 1.2/1.8/3.3

Key Features

  • not available in standard regulators. Incorporating the ability for selfcalibration when paired with selected ESS DACs to help maintain constant output levels. Internal fixed mode that supports +1.2V/+1.8V/+3.3V/+4.5V presets to help simplify device configuration for standard voltages. External fixed mode which allows for output adjustment to a flexible reference voltage. As an example, the ES9312Q enables ESS Technology’s DACs to achieve up to +140dB DNR and THD+N of -122dB with the ES9039PRO a.
