The REF19x series uses a patented temperature drift curvature correction circuit and laser-trimmed thin-film resistors to achieve very low temperature coefficient and high initial accuracy. The E-grade device offers +\/-2mV initial accuracy (0.08%) and 2ppm\/C temperature coefficient over the -40C to +85C range. The device operates from supplies as low as 3.3V (0.8V dropout at 10mA) and draws only 45uA maximum supply current. A SLEEP pin allows the output to be disabled, reducing supply current to 15uA maximum. The output can source up to 30mA with short-circuit protection. The output requires a 1uF capacitor for stability. The device is ideal for precision ADC\/DAC references, smart sensors, and battery-powered instruments where low power consumption and high accuracy are critical.","working_principle":"The REF192ESZ-REEL is a series-mode bandgap voltage reference. (1) Bandgap Core: The core circuit generates a stable 2.5V output by summing a PTAT (proportional to absolute temperature) voltage with a complementary-to-absolute-temperature (CTAT) voltage from a forward-biased diode. When properly trimmed, the temperature coefficients cancel, producing a nearly flat VOUT vs. temperature characteristic. (2) Curvature Correction: The patented curvature correction circuit adds a higher-order temperature compensation term that corrects for the nonlinear residual temperature drift of the basic bandgap, reducing the temperature coefficient to 2ppm\/C. (3) Laser Trimming: Thin-film resistors are laser-trimmed during manufacturing to achieve the +\/-2mV initial accuracy at 25C. (4) Sleep Mode: When the SLEEP pin is driven low (below 0.8V), the output stage is disabled and the supply current drops to 15uA maximum. This is useful for power-cycled applications. (5) Output: The series architecture allows the output to source up to 30mA. The output impedance is very low, providing excellent load regulation of 4-10 ppm\/mA.","pin_description":"
