REF2030AIDDCR

Overview

The REF2030AIDDCR is a dual-output voltage reference from the Texas Instruments REF20xx series, housed in a SOT-23-Thin-5 package. It provides a primary reference voltage (VREF) of 3 V and a secondary bias output (VBIAS) equal to half the reference voltage (1.5 V). The device features an initial accuracy of ±0.05% and a maximum temperature coefficient of 8 ppm/°C across the -40°C to +125°C operating range. It operates with a supply voltage between 2.52 V and 5.5 V, drawing a typical quiescent current of 360 μA. The unit supports a maximum output current of ±20 mA.

Feature Summary

• Dual-output architecture providing both VREF and VREF/2 for single-supply system biasing
• High precision with ±0.05% initial accuracy and low drift of 8 ppm/°C
• Low power consumption with 360 μA quiescent current and 5 μA shutdown mode
• Compact SOT-23-Thin-5 footprint suitable for space-constrained designs

Applications

• Analog-to-digital converter (ADC) input biasing in single-supply systems
• Precision industrial measurement instrumentation
• Data acquisition systems requiring stable reference voltages
• Battery-powered devices utilizing low dropout operation

Procurement Notes

Verify the specific suffix 'AIDD' corresponds to the required accuracy grade and packaging configuration. Confirm that the SOT-23-Thin-5 form factor matches the target PCB layout constraints. Ensure the 3 V output specification aligns with the downstream circuit requirements. Check for any moisture sensitivity level restrictions during assembly processing.

Selection Notes

Select this component when a dual-output reference is needed to simplify bias networks in ADC applications. The 8 ppm/°C drift ensures stability over wide temperature ranges. Consider the 360 μA quiescent current for battery life calculations. The ±20 mA output capability allows direct driving of moderate loads without additional buffering.

Part Context

Part of the REF20xx family of low-drift, low-power voltage references. This series includes variants with different output voltages such as 2.5 V, 3.3 V, and 4.096 V. All members share the same dual-output topology and high-precision characteristics, designed to replace discrete resistor divider solutions.

Replacement Considerations

Direct functional substitutes within the same series include REF2025AIDDCR (2.5 V), REF2033AIDDCR (3.3 V), and REF2041AIDDCR (4.096 V). These parts share identical pinouts and performance specifications except for the output voltage levels.
