Product details
Overview
ADR130AUJZ-REEL7 from Analog Devices is a precision sub-band gap voltage reference IC delivering 0.5 V or 1.0 V output with ±0.70% initial accuracy (A grade), 50 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/source load current - ideal for low-power, high-stability analog signal chains in portable instrumentation.
For engineers reviewing the ADR130AUJZ-REEL7 datasheet, ADR130AUJZ-REEL7 pinout, ADR130AUJZ-REEL7 application, or ADR130AUJZ-REEL7 equivalent, key selection criteria include output voltage configuration (SET-to-VOUT or SET-to-GND), thermal drift performance across −40°C to +125°C, noise floor (3 µV p-p at 0.5 V), load regulation (±0.13 mV/mA sourcing), and compatibility with 0.1 µF output capacitance for stability.
Technical Context
The ADR130AUJZ-REEL7 implements a proprietary curvature-corrected sub-band gap architecture to minimize nonlinearities in output voltage vs. temperature. Its dual-output capability (0.5 V or 1.0 V) is determined solely by external connection of Pin 5 (SET) to either Pin 4 (VOUT) or Pin 2 (GND), requiring no internal trimming or external resistors.
It features micropower operation (75–150 µA quiescent current over temperature), low-noise design (3 µV p-p, 0.1 Hz–10 Hz, at 0.5 V), and robust transient response (80 µs turn-on settling to 0.1%). Input voltage range (2.0 V–18 V) and ±2 mA sinking capability enable use in both low-voltage battery systems and higher-supply industrial nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 0.5 V (SET tied to VOUT) or 1.0 V (SET tied to GND); fixed, resistorless selection |
| Initial Accuracy | ±0.70% max (A grade); ensures ≤ ±3.5 mV error at 0.5 V or ≤ ±7.0 mV at 1.0 V at 25°C |
| Tempco | 50 ppm/°C max (−40°C to +125°C); contributes ≤ ±4.25 mV drift over full range at 0.5 V |
| Quiescent Current | 75–150 µA over temperature; enables >10-year battery life in 10 µA-systems with duty cycling |
| Output Noise | 3 µV p-p (0.1 Hz–10 Hz, 0.5 V mode); critical for 16-bit+ SAR ADC reference stability |
| Load Regulation | ±0.13 mV/mA (source, 0–4 mA); maintains < 0.5 LSB error in 16-bit 5 V full-scale systems |
| Line Regulation | ±40 ppm/V (2–18 V); limits input ripple sensitivity to < 0.2 mV per volt of supply variation |
Pinout & Package
ADR130AUJZ-REEL7 is housed in a Pb-free, 6-lead TSOT (UJ-6) package measuring 2.90 mm × 1.60 mm × 0.90 mm (max height), optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (NC) | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| Pin 2 (GND) | Analog Ground Reference | Primary return path for reference output and internal bias; requires low-impedance plane tie |
| Pin 3 (VIN) | Input Supply | Accepts 2.0–18 V DC; no input capacitor required but 1 µF improves transient immunity |
| Pin 4 (VOUT) | Reference Output | Delivers stable 0.5 V or 1.0 V; requires 0.1 µF ceramic capacitor to ground for stability |
| Pin 5 (SET) | Output Configuration Control | Tie to VOUT for 0.5 V mode; tie to GND for 1.0 V mode - defines output without external components |
| Pin 6 (NC) | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|

| Micropower operation | 80 µA typical IQ enables direct integration into always-on sensor nodes and energy-harvesting systems with µW budgets |
| Low-noise 0.1 Hz–10 Hz band | 3 µV p-p at 0.5 V output meets stringent requirements for precision weigh scales and medical front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What output voltage does ADR130AUJZ-REEL7 deliver, and how is it selected?
The ADR130AUJZ-REEL7 delivers either 0.5 V or 1.0 V, selected exclusively by external connection: tie Pin 5 (SET) to Pin 4 (VOUT) for 0.5 V output, or tie Pin 5 to Pin 2 (GND) for 1.0 V output. No external resistors or programming are required. This resistorless configuration is defined in the ADR130 datasheet Rev. D, Tables 1 and 2, and Figure 32/33.
Is ADR130AUJZ-REEL7 pin-compatible with other ADR130 variants like ADR130BUJZ-REEL7?
Yes, ADR130AUJZ-REEL7 is fully pin-compatible with ADR130BUJZ-REEL7 and all UJ-6 packaged ADR130 variants. Both share identical 6-lead TSOT (UJ-6) footprint, pinout, and electrical interface. The only differences are grade-specific parameters: ADR130AUJZ-REEL7 has ±0.70% initial accuracy and 50 ppm/°C max tempco, while the B grade offers tighter tolerances.
What is the minimum recommended output capacitor for ADR130AUJZ-REEL7 stability?
A 0.1 µF ceramic capacitor is required between Pin 4 (VOUT) and Pin 2 (GND) for guaranteed stability across all operating conditions. The ADR130 datasheet Rev. D (Page 12, "Output Capacitor") states this value is mandatory; larger values (up to 1 µF) may improve load transient response but increase turn-on settling time.
Can ADR130AUJZ-REEL7 operate from a 2.0 V supply?
Yes, ADR130AUJZ-REEL7 is fully specified to operate with VIN as low as 2.0 V across the full −40°C to +125°C temperature range. Figure 4 and Figure 7 in the datasheet confirm minimum input voltage remains ≤2.0 V even at maximum load (4 mA) and extreme temperatures, enabling use in single-cell Li-ion or NiMH systems.
Does ADR130AUJZ-REEL7 support sinking current, and how much?
Yes, ADR130AUJZ-REEL7 supports sinking up to −2 mA while maintaining specified accuracy and regulation. Electrical Characteristics tables (Pages 3–4) list sink load regulation as ±1.0 mV/mA (0.5 V mode) and ±2.0 mV/mA (1.0 V mode), confirming robust performance when used to bias current-sinking sensor interfaces or pull-down circuits.
