REF2041AIDDCT

Источник опорного напряжения, малой мощности, двойной выход, REF2041, 4.096В, SOT-23-5.

The REF2041 series dual-output low-power Voltage Reference for use with single-supply systems. Applications with only a positive supply voltage often require additional stable voltage in the middle of the analog-to-digital converter (ADC) input range to bias input bipolar signals. The REF20xx provides a reference voltage (VREF) for the ADC and a second highly-accurate voltage (VBIAS) that can be used to bias the input bipolar signals. The REF20xx offers excellent temperature drift (8ppm/°C maximum) and initial accuracy (0.05%) on both the VREF and VBIAS outputs while operating at a quiescent current less than 430µA. In addition, the VREF and VBIAS outputs track each other with a precision of 6ppm/°C (maximum) across the temperature range of -40 to 85°C. Extremely low dropout voltage of only 10mV allows operation from very low input voltages, which can be very useful in battery-operated systems.
