Output noise is 3µVp-p from 0.1Hz to 10Hz, which keeps the reference contribution below the quantization noise floor of a 2.048V full-scale, 20-bit system (about 2µV LSB). The low-frequency noise dominates the signal chain in DC-coupled precision measurements, not the wideband noise. ## Output drive and input rail tolerance Rated for 10mA output current, the REF5020AIDGKT can source the dynamic load of a successive-approximation ADC's reference input without an external buffer — the internal amplifier settles within the ADC's acquisition window. The 1.2mA quiescent supply current means the reference's own draw is a small fraction of the total system budget in a battery-powered instrument. The series topology means the output tracks the input until dropout; below 2.7V the output falls out of regulation, so the supply rail must stay above that floor across the full load and temperature range. ## Package, temperature grade, and lifecycle The base product number REF5020 covers a family of output voltages; the AIDGKT suffix identifies the 2.048V variant in the 8-VSSOP package on tape-and-reel or cut-tape.","metaTitle":"TI REF5020AIDGKT Voltage Reference, 2.048V, ±0.1%, 8-VSSOP","metaDescription":"Texas Instruments REF5020AIDGKT series voltage reference, fixed 2.048V output, ±0.1% tolerance, 3µVp-p noise.
