Product details
Overview
ADR130BUJZ-REEL7 from Analog Devices is a precision sub-band gap voltage reference IC delivering 1.0 V or 0.5 V output with ±0.35% initial accuracy (B grade), 25 ppm/°C max temperature coefficient, and 80 µA typical quiescent current in a 6-lead TSOT package. It operates from 2.0 V to 18 V input and supports ±2 mA sink / +4 mA source load current, serving as a stable reference for high-resolution ADCs and portable instrumentation.
For engineers reviewing the ADR130BUJZ-REEL7 datasheet, ADR130BUJZ-REEL7 pinout, ADR130BUJZ-REEL7 application, or ADR130BUJZ-REEL7 equivalent, key selection criteria include output voltage configuration (SET-to-GND for 1.0 V), low-noise performance (6 µV p-p, 0.1–10 Hz), long-term stability (100 ppm/1000 hrs), and industrial temperature range (−40°C to +125°C).
Technical Context
The ADR130BUJZ-REEL7 implements a proprietary temperature drift curvature correction technique to minimize nonlinearities in VOUT vs. temperature, achieving 25 ppm/°C max TCVO across −40°C to +125°C. Its architecture enables stable operation with only a 0.1 µF output capacitor and no mandatory input capacitor.
Output voltage is configured by connecting SET (Pin 5) to GND for 1.0 V (B grade: 0.9965 V to 1.0035 V) or to VOUT for 0.5 V (B grade: 0.49825 V to 0.50175 V). Load regulation is ±0.25 mV/mA (source) and ±2.0 mV/mA (sink) over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.0 V (SET tied to GND); precise enough for 12-bit+ SAR ADC reference without trimming |
| Initial Accuracy | ±0.35% (B grade); corresponds to ±3.5 mV error at 1.0 V output |
| Temp Coefficient | 25 ppm/°C max; adds ≤0.3 mV drift over −40°C to +125°C span at 1.0 V |
| Quiescent Current | 85 µA typical (no load); enables >10-year battery life in 10 µA-systems with duty cycling |
| Voltage Noise | 6 µV p-p (0.1–10 Hz); critical for low-frequency precision measurements and weigh-scale front-ends |
| Load Current Range | +4 mA / −2 mA; sufficient to drive ADC reference inputs and small op-amp bias networks |
| Input Voltage Range | 2.0 V to 18 V; supports direct connection to Li-ion batteries (3.0–4.2 V) and industrial 12 V rails |
Pinout & Package
ADR130BUJZ-REEL7 is housed in a Pb-free 6-lead TSOT package (UJ-6), measuring 2.90 mm × 1.60 mm × 0.95 mm (max height), with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 | No Connect (NC) | Unbonded pins; must be left floating or grounded per layout best practice - no electrical function |
| 2 | GND | Analog ground reference; requires low-impedance connection to system AGND plane |
| 3 | VIN | Input supply rail; accepts 2.0–18 V; internal pass element regulates to stable VOUT |
| 4 | VOUT | Regulated output; 1.0 V when SET = GND; 0.5 V when SET = VOUT; decoupled with 0.1 µF ceramic |
| 5 | SET | Voltage configuration node; tie to GND for 1.0 V output, or to VOUT for 0.5 V output |
Key Features
| Feature | Design Value |
|---|---|
| Curvature-corrected TCVO | 25 ppm/°C max (B grade) achieved via on-die analog compensation - eliminates need for external calibration |
| Dual-output configurability | Single device supports either 0.5 V or 1.0 V output via SET pin routing - reduces BOM count vs. fixed-output alternatives |
| Micropower operation | 85 µA typical IQ enables use in always-on sensor nodes where average current <100 µA is mandatory |
| Low-noise architecture | 6 µV p-p (0.1–10 Hz) at 1.0 V output - meets noise floor requirements for 24-bit delta-sigma ADC references |
| Robust transient response | 80 µs turn-on settling to 0.1%; stable with 0.1 µF output cap - simplifies layout and eliminates need for larger ceramics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3410ARJZ-R7 | Fixed 1.0 V output, 10 ppm/°C max TCVO, 4.5 µA IQ, SOT-23-5 package | Lower drift but higher sensitivity to input ripple due to ultra-low IQ; no SET-pin flexibility | Select when lowest possible drift dominates over configurability and load drive capability |
| REF3310AIDBZR | Fixed 1.0 V, 30 ppm/°C max TCVO, 3.9 µA IQ, SOT-23-3 package, no SET pin | Limited to 5 mA max load; lacks dual-output option and curvature correction; smaller footprint | Choose for cost-sensitive, space-constrained designs where 30 ppm/°C is acceptable and 0.5 V output not required |
Compared with ADR3410ARJZ-R7 and REF3310AIDBZR, the ADR130BUJZ-REEL7 offers unique SET-pin configurability (0.5 V/1.0 V), superior load drive (+4 mA/−2 mA), and curvature-corrected 25 ppm/°C performance - making it optimal for multi-voltage reference systems and industrial-grade portable instruments.

FAQ
What output voltage does ADR130BUJZ-REEL7 deliver, and how is it set?
The ADR130BUJZ-REEL7 delivers either 0.5 V or 1.0 V depending on the SET pin connection: tie SET (Pin 5) to VOUT (Pin 4) for 0.5 V output, or to GND (Pin 2) for 1.0 V output. For the B grade, the 1.0 V output is guaranteed between 0.9965 V and 1.0035 V at 25°C. This dual-output flexibility is built into the ADR130BUJZ-REEL7 silicon and requires no external components.
What is the maximum load current supported by ADR130BUJZ-REEL7?
The ADR130BUJZ-REEL7 supports +4 mA source current and −2 mA sink current across −40°C to +125°C. Load regulation remains within ±0.25 mV/mA (source) and ±2.0 mV/mA (sink) under those conditions. This capability allows the ADR130BUJZ-REEL7 to directly drive ADC reference inputs, op-amp bias networks, and small DAC loads without external buffers.
Does ADR130BUJZ-REEL7 require an input capacitor?
No, the ADR130BUJZ-REEL7 does not require an input capacitor for stability. However, adding a 1 µF to 10 µF ceramic capacitor (plus optional 0.1 µF parallel) improves transient response during supply voltage steps. The ADR130BUJZ-REEL7's internal design eliminates input capacitance dependency - a key differentiator from older bandgap references that mandate minimum Cin values.
How does the temperature coefficient of ADR130BUJZ-REEL7 compare to standard bandgap references?
The ADR130BUJZ-REEL7 achieves 25 ppm/°C max temperature coefficient (B grade) using proprietary curvature correction, significantly better than conventional bandgap references (typically 50–100 ppm/°C). This is confirmed across −40°C to +125°C in Table 2 of the datasheet and validated in Figure 6. The ADR130BUJZ-REEL7's TCVO remains linear and bounded - enabling high-accuracy systems without software compensation.
Can ADR130BUJZ-REEL7 be used to generate a precision current source?
Yes, the ADR130BUJZ-REEL7 can be configured as a precision floating current source by bootstrapping its output across a set resistor (RSET), as shown in Figure 36 of the datasheet. With this topology, the ADR130BUJZ-REEL7 delivers highly accurate currents from ~85 µA up to 4 mA, maintaining stability and low noise - ideal for sensor excitation and calibrated LED biasing.
