Detailed Description

Precision series voltage reference, 2.048 V output, XFET technology, 8-SOIC package, surface-mount. Designed for stable, low-noise, low-drift reference generation for high-resolution ADCs/DACs and precision measurement systems. Base product family ADR420. Supplied in tube packaging. Main Category: Integrated Circuits (ICs). Small Classification: PMIC – Voltage Reference.

Key Features

2.048 V precise reference for easy binary scaling (ideal for 12-bit, 16-bit converters)

XFET architecture for low noise and excellent stability

Low temperature drift (ppm/°C class; see datasheet for exact grade limits)

Tight initial accuracy (factory trimmed; see datasheet for grade-specific accuracy)

Strong line and load regulation for stable operation across supply and load changes

Low long-term drift for sustained accuracy over time

Low quiescent current for power-sensitive designs

8-lead SOIC, standard footprint, easy to assemble (SMT)

ADR420 family consistency across related output voltages

Key Advantages

Better measurement integrity due to low noise and drift

Simplified design for binary-weighted ADC scales with 2.048 V output

Reliable performance across temperature and time for precision instruments

Drop-in convenience with widely used SOIC-8 footprint

Lower system calibration overhead thanks to factory trim and stability
