That 2.048V level is a natural fit for bipolar ADC input ranges (±2.048V) and for driving the reference input of successive-approximation or delta-sigma converters where the reference noise floor directly sets the system SNR. ## Noise floor and drift — the specs that matter for converter performance Output noise is specified at 3 µVp-p over the 0.1 Hz to 10 Hz band — the frequency range where 1/f noise dominates and where a precision ADC's reference input is most sensitive. A noisy reference here costs effective bits before the converter even sees the signal. The 3 ppm/°C drift means the reference voltage shifts less than 1.5 mV over the full temperature range, keeping the ADC transfer function stable across industrial thermal cycling. The series architecture (no load-dependent dropout) delivers 10 mA output current with a 1.2 mA quiescent supply current.","metaTitle":"REF5020IDR 2.048V Precision Voltage Reference, 3 ppm/°C","metaDescription":"TI REF5020IDR series voltage reference: fixed 2.048V output, ±0.05% tolerance, 3µVp-p noise, 3 ppm/°C drift, -40 to 125°C.
