Product details
Overview
ADR130AUJZ-R2 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-accuracy analog signal conditioning in portable instrumentation.
For engineers reviewing the ADR130AUJZ-R2 datasheet, ADR130AUJZ-R2 pinout, ADR130AUJZ-R2 application, or ADR130AUJZ-R2 equivalent, key selection criteria include output voltage configuration (SET-to-VOUT or SET-to-GND), thermal drift performance across −40°C to +125°C, stability with 0.1 µF output capacitance, and micropower operation under varying load and line conditions.
Technical Context
The ADR130AUJZ-R2 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 Pin 4 (VOUT) or Pin 2 (GND), with no internal trimming or configuration registers.
It requires no input capacitor but mandates a 0.1 µF ceramic output capacitor for stability; additional parallel capacitance (up to 1 µF) improves load transient response without affecting regulation. The device exhibits 3 µV p-p (0.1–10 Hz) noise at 0.5 V output and 6 µV p-p at 1.0 V output, with turn-on settling time of 80 µs to 0.1%.
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 dual-option output set by external connection only |
| Initial Accuracy | ±0.70% max (A grade) - ensures ≤ ±3.5 mV error at 0.5 V or ≤ ±7.0 mV at 1.0 V over full temperature range |
| Temp. Coefficient | 50 ppm/°C max (A grade) - guarantees ≤ ±6.25 mV drift over −40°C to +125°C at 0.5 V output |

| Load Current | +4 mA / −2 mA - supports driving 12-bit SAR ADC references or low-current DAC bias networks directly |
| Output Noise | 3 µV p-p (0.1–10 Hz) at 0.5 V - meets <1 LSB noise floor for 16-bit 0.5 V full-scale measurements |
| Input Range | 2.0 V to 18 V - allows direct use from single Li-ion cells up to industrial 12 V rails without LDO pre-regulation |
Pinout & Package
ADR130AUJZ-R2 is housed in a Pb-free 6-lead TSOT package (UJ-6), 2.90 mm × 1.60 mm × 0.95 mm, compliant with JEDEC MO-193-AA (height/thickness exceptions). Thermal resistance θJA = 186°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 | No Connect (NC) | Internally unconnected; must remain floating - no routing or grounding permitted |
| 2 | GND | Analog ground reference; requires low-impedance star connection to system AGND plane |
| 3 | VIN | Unregulated input supply (2.0–18 V); accepts ripple up to 100 mVp-p without degradation |
| 4 | VOUT | Stable 0.5 V or 1.0 V reference output; must be decoupled with 0.1 µF ceramic capacitor to GND |
| 5 | SET | Configuration terminal: tie to VOUT for 0.5 V output; tie to GND for 1.0 V output - no resistors or active drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3450ARJZ-R7 | Fixed 5.0 V output; 0.1% initial accuracy; 3 ppm/°C TCVO; 120 µA IQ; SOT-23-5 package | Higher output voltage and tighter TCVO, but incompatible pinout and no dual-voltage configurability | Select when 5.0 V reference is required and ultra-low drift outweighs micropower needs |
| REF3312AIDBZR | Fixed 1.2 V output; 0.2% initial accuracy; 10 ppm/°C TCVO; 3.8 µA IQ; SOT-23-3 package | Lower IQ and better TCVO, but lacks 0.5 V option, SET configuration, and ±2 mA sink capability | Select for ultra-low-power 1.2 V systems where 0.5 V output and sink current are not needed |

FAQ
What output voltages does the ADR130AUJZ-R2 support, and how is selection implemented?
The ADR130AUJZ-R2 supports two precise output voltages: 0.5 V and 1.0 V. Selection is achieved exclusively through external connection of Pin 5 (SET) - tie SET to Pin 4 (VOUT) for 0.5 V output, or tie SET to Pin 2 (GND) for 1.0 V output. No internal programming, resistors, or additional components are required. This passive configuration method ensures deterministic behavior and eliminates firmware dependencies in the ADR130AUJZ-R2 design.
What is the minimum recommended output capacitor for stable operation of the ADR130AUJZ-R2?
The ADR130AUJZ-R2 requires a minimum 0.1 µF ceramic capacitor connected between Pin 4 (VOUT) and Pin 2 (GND) for guaranteed stability across all operating conditions. This capacitor must be placed within 2 mm of the device pins. Larger values (up to 1 µF) may be added in parallel to improve load transient response, but doing so increases turn-on settling time beyond the specified 80 µs. The ADR130AUJZ-R2 will not oscillate or become unstable with the 0.1 µF capacitor properly installed.
Can the ADR130AUJZ-R2 drive a 10 kΩ load while maintaining its specified accuracy?
Yes - the ADR130AUJZ-R2 can drive a 10 kΩ load (100 µA at 1.0 V) while maintaining full accuracy. Its specified load regulation is ±0.25 mV/mA (source) and ±2.0 mV/mA (sink) over −40°C to +125°C, meaning a 100 µA load shift introduces ≤ ±0.025 mV error at 1.0 V output. Since the ADR130AUJZ-R2's initial accuracy is ±7.0 mV (A grade), this load-induced error represents <0.4% of total error budget and remains well within specification.
Does the ADR130AUJZ-R2 require an input capacitor, and what happens if one is omitted?
No, the ADR130AUJZ-R2 does not require an input capacitor for stability or basic operation. Omitting it has no adverse effect on regulation, noise, or accuracy under steady-state conditions. However, adding a 1 µF–10 µF input capacitor (with optional 0.1 µF parallel) improves transient response to sudden VIN changes - such as battery insertion or switching regulator ripple - reducing output perturbation by up to 70% per Figure 26 and Figure 29 in the ADR130AUJZ-R2 datasheet.
How does the ADR130AUJZ-R2 achieve its low temperature coefficient despite using a sub-band gap topology?
The ADR130AUJZ-R2 achieves low temperature coefficient via a proprietary curvature-correction technique integrated into its sub-band gap core. Unlike conventional band gap references that exhibit parabolic drift, this technique actively compensates second-order thermal effects, reducing the dominant nonlinearity in VO vs. temperature. As confirmed in Figures 2 and 5 of the ADR130AUJZ-R2 datasheet, this results in measured TCVO as low as 15 ppm/°C typical - significantly better than the 50 ppm/°C maximum spec - across the full −40°C to +125°C range.
