The ADR38x family uses a bandgap architecture with curvature correction: the core generates a PTAT (Proportional To Absolute Temperature) voltage and a CTAT (Complementary To Absolute Temperature) voltage, which are summed to produce a near-zero temperature coefficient. The ADR381 achieves 25ppm\/C maximum temperature drift (B-grade) over -40C to +85C, meaning the output shifts at most 2.5mV over the full temperature range. The output can source 5mA and sink 0.5mA, sufficient for ADC\/DAC reference inputs and bias networks. The quiescent current is only 100uA, making it suitable for battery-powered devices. The output noise is 5uVpp from 0.1-10Hz, and 40uVrms from 10Hz-10kHz, low enough for 12-14 bit ADCs. The line regulation is 20ppm\/V (output changes 50uV per 1V input change), and the load regulation is 50ppm\/mA. The device requires no external capacitor for stability, but a 0.1uF ceramic on VOUT improves noise and transient response. The turn-on time is 5ms to 0.1% of final value. The ADR381 output is 2.500V, ideal for 2.5V ADC\/DAC full-scale references. The -ARTZ-REEL7 suffix specifies SOT-23-5, tape-and-reel (3000 pcs). The SOT-23-5 package provides 0.8mm pitch, suitable for compact PCB layouts.","pin_description":"
