The REF101 is a precision voltage reference which provides a +10.00V output. The drift is laser-trimmed to 1ppm/°C max (KM grade) over the full specification range. This is in contrast to some references which guarantee drift over a limited portion of their specification temperature range. The REF101 achieves its precision without a heater. This results in low quiescent current (4.5mA typ), fast warm-up (1ms to 0.1%), excellent stability (50ppm/1000hrs typ), and low noise (25mVp-p max, 0.1Hz to 10Hz). The output can be adjusted with minimal effect on drift or stability. Additionally, the REF101 contains a matched pair of user-accessible precision 20kW resistors which are useful in a variety of applications. Single supply operation over 13.5V to 35V supply range and excellent overall specifications make the REF101 an ideal choice for the most demanding applications such as precision system standards, D/A and A/D references, transducer excitation etc.
