ES9312 Datasheet | ESS Technology

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 +140d B DNR and THD+N of -122d B with the ES9039PRO and allows for various voltage outputs to be configured through a simple pin configuration. The ES9312Q is available in a small 16-pin, 3mm x 3mm QFN package providing a cost effective solution. FEATURE DESCRIPTION Ultra low noise regulated to 180m A per output at Excellent line and load regulation for output current to maintain peak multiple voltage levels performance 1µVrms output noise (10Hz to 100k Hz) 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 1.2/1.8/3.3/4.5V output Both regulator voltages are configurable with external resistors Dual regulators in one package Reducing BOM requirements and setup Operating supply Supply voltage of +5V Low pin count packaging 3mm x 3mm, 16 pin QFN, minimizing PCB footprint and board space APPLICATIONS - ESS SABRE DAC Supply in Calibration Mode with Calibration Resistor - General Ultra-Low Noise Supply for DACs and ADCs ESS TECHNOLOGY, INC. 109 Bonaventura Drive, San Jose, CA 95134, USA Tel (408) 643-8800 - .ESSTECH.
