This level of accuracy means the reference output stays within 1.5 mV of 2.5 V at 25 °C without any external trim — critical for a precision ADC's Vref pin or a DAC's full-scale accuracy budget. For a 16-bit ADC with a 2.5 V reference, that drift contributes well under 1 LSB of error across temperature. ## Input headroom and output drive The series topology means quiescent current is only 600 µA, which is independent of the load current. Output current capability is 30 mA, enough to bias multiple ADC inputs, an external buffer, or a small sensor bridge. ## Noise floor for precision signal chains For a 2.5 V reference feeding a 24-bit sigma-delta ADC, this noise floor is low enough that the converter's own quantization noise dominates the signal chain — no additional filtering needed between the reference output and the ADC's Vref pin. The tube packaging (standard for 8-SOIC) is the factory-shipped format — compatible with pick-and-place after tube-to-tape conversion if needed.","metaTitle":"MAX6143AASA25+ Analog Devices Voltage Reference, 2.5V, 0.06%","metaDescription":"MAX6143AASA25+ series voltage reference, 2.5V fixed output, ±0.06% tolerance, 3ppm/°C tempco, 8-SOIC.
