Description

TheADR121/ADR125/ ADR127 are a family of micropower, high precision, series mode, band gap references with sink and source capability. The parts feature high accuracy and low power consumption in a tiny package. The ADR12x design includes a patented temperature-drift curvature correction technique that minimizes the nonlinearities in the output voltage vs. temperature characteristics.The ADR12x is a low dropout voltage reference, requiring only 300 mV for ADR121 / ADR125 and 1.45 V for ADR127 above the nominal output voltage on the input to provide a stable output voltage. This low dropout performance, coupled with the low 85 μA operating current, makes the ADR12x ideal for battery-powered applications.Available in an extended industrial temperature range of −40°C to +125°C, the ADR121 / ADR125 / ADR127 are housed in the tiny TSOT (UJ-6) package.APPLICATIONSBattery-powered instrumentationPortable medical equipmentData acquisition systemsAutomotive
