Product details
Overview
ADR510ARTZ-REEL7 from Analog Devices is a precision 1.000 V shunt voltage reference in a 3 mm × 3 mm SOT-23-3 package, delivering ±0.35% initial accuracy, 70 ppm/°C max temperature coefficient, 4 μV p-p (0.1 Hz to 10 Hz) output noise, and stable operation from 100 μA to 10 mA. It serves as a low-noise, space-constrained reference for high-resolution ADCs and battery-powered instrumentation.
For engineers reviewing the ADR510ARTZ-REEL7 datasheet, ADR510ARTZ-REEL7 pinout, ADR510ARTZ-REEL7 application, or ADR510ARTZ-REEL7 equivalent, key selection criteria include its trim-capable 1.0 V output, ultralow noise floor, absence of required external capacitor, SOT-23-3 footprint compatibility, and −40°C to +85°C industrial temperature range.
Technical Context
The ADR510ARTZ-REEL7 operates as a two-terminal shunt reference with cathode (V+) and anode (V−) terminals plus a TRIM/NC terminal, requiring an external bias resistor for current regulation. Its internal bandgap-derived topology achieves 70 ppm/°C tempco over 0°C to 70°C and 85 ppm/°C over full −40°C to +85°C range.
It delivers 1.000 V nominal output with ±3.5 mV (±0.35%) initial error at 25°C, maintains 0.3 Ω max dynamic output impedance, and settles within 10 μs to 0.1% of final value without load capacitance-enabling direct integration into precision data converter reference paths and portable medical sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.000 V ±3.5 mV - enables accurate scaling for 8-/12-bit converters with minimal system calibration. |
| Initial Accuracy | ±0.35% - ensures ≤3.5 mV absolute error at 25°C, reducing offset correction burden in production test. |
| Tempco | 70 ppm/°C max (0°C to 70°C) - limits drift to ±0.49 mV over 70°C span, critical for unheated industrial sensors. |
| Output Noise | 4 μV p-p (0.1 Hz–10 Hz) - preserves SNR in high-gain, low-frequency signal chains like ECG front-ends. |
| Operating Current | 100 μA to 10 mA - supports ultra-low-power sleep modes and robust full-range operation in mixed-signal SoCs. |
| Output Impedance | 0.3 Ω max - minimizes load-induced voltage shift under dynamic current draw from SAR ADC reference inputs. |
| Turn-On Time | 10 μs to 0.1% - allows fast wake-up in duty-cycled portable instruments without reference settling delay penalties. |
Pinout & Package
ADR510ARTZ-REEL7 uses a 3-lead SOT-23-3 (RT-3) package measuring 3.04 mm × 2.90 mm × 1.12 mm, compliant with JEDEC TO-236-AB. Pin 1 = V+ (cathode), Pin 2 = V− (anode), Pin 3 = TRIM/NC (no-connect by default; enables ±0.5% output adjustment when externally biased).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Cathode terminal | Reference output node; must be connected via RBIAS to supply rail; sinks total current (IL + IQ). |
| V− | Anode terminal | Ground reference point; establishes 1.0 V potential difference across device; ties to system GND or negative rail. |
| TRIM/NC | Adjustment terminal | Open-circuit by default; when used with potentiometer, permits ±0.5% fine-tuning of VOUT without degrading tempco. |
Key Features
| Feature | Design Value |
|---|---|
| No external capacitor required | Stable with any capacitive load; eliminates BOM item and PCB area for decoupling cap in space-constrained designs. |
| Ultralow 4 μV p-p noise | Enables <16-bit ENOB preservation in 12-bit+ data acquisition systems without post-reference filtering. |
| TRIM terminal for ±0.5% adjustment | Allows system-level calibration to cancel PCB trace resistance, op-amp input offset, or DAC gain errors. |
| 100 μA minimum operating current | Supports >10-year battery life in coin-cell-powered IoT sensors while maintaining 1.0 V reference integrity. |
| SOT-23-3 footprint | Direct drop-in replacement for legacy shunt references (e.g., LM4040 series) using standard pick-and-place equipment. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C10IDBZR | 1.0 V output, ±0.5% initial accuracy, 100 ppm/°C tempco, 20 μV p-p noise, SOT-23-3 | Higher noise and looser accuracy limit use in ≥12-bit systems; no TRIM pin | Select when cost sensitivity outweighs precision requirements and system calibration is performed digitally. |
| MAX6126AASA10+ | 1.0 V output, ±0.06% initial accuracy, 3 ppm/°C tempco, 1.2 μV p-p noise, SO-8 package | Superior specs but larger SO-8 footprint and higher quiescent current (350 μA min) | Select when ultimate precision justifies board area and power budget; not suitable for space-constrained handhelds. |

FAQ
What is the exact output voltage tolerance of the ADR510ARTZ-REEL7 at 25°C?
The ADR510ARTZ-REEL7 has a guaranteed initial output voltage of 1.000 V ±3.5 mV (±0.35%) at 25°C, as specified in Table 2 of the Rev. B datasheet. This tolerance is measured under 100 μA to 10 mA input current conditions and defines the absolute accuracy before system-level trimming. The ADR510ARTZ-REEL7 achieves this via laser-trimmed bandgap circuitry, ensuring consistent performance across production lots without requiring external calibration for basic 12-bit applications.
Does the ADR510ARTZ-REEL7 require an external capacitor for stability?
No, the ADR510ARTZ-REEL7 does not require an external capacitor for stability-it is internally compensated and remains stable with any capacitive load on its output. This design eliminates a common BOM item and PCB footprint, simplifying layout in dense portable designs. However, an optional capacitor may be added for additional high-frequency noise filtering, as noted in Figure 2 and Applications Information section of the ADR510ARTZ-REEL7 datasheet.
What is the function of the TRIM/NC pin on the ADR510ARTZ-REEL7?
Pin 3 (TRIM/NC) on the ADR510ARTZ-REEL7 is a dedicated adjustment terminal that enables ±0.5% fine-tuning of the 1.0 V output voltage without degrading temperature coefficient performance. When left unconnected, it functions as NC (no connect). When used with a 10 kΩ potentiometer as shown in Figure 12, it allows system-level calibration to compensate for PCB trace resistance, op-amp offset, or DAC gain errors-making the ADR510ARTZ-REEL7 adaptable to real-world board-level tolerances.
Can the ADR510ARTZ-REEL7 be used to generate a precise negative reference voltage?
Yes, the ADR510ARTZ-REEL7 can be configured as a precise −1.0 V reference by connecting its V+ (cathode) to ground and its V− (anode) to a negative supply rail through a bias resistor (R1), as illustrated in Figure 14. Because the ADR510ARTZ-REEL7 behaves like a Zener diode, this arrangement forces the anode to sit at −1.0 V relative to ground. R1 must supply 100 μA to 10 mA to maintain regulation, enabling use in bipolar data converter interfaces and precision op-amp bias networks.
What is the maximum operating temperature range supported by the ADR510ARTZ-REEL7?
The ADR510ARTZ-REEL7 is rated for continuous operation from −40°C to +85°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings tables. Its temperature coefficient is specified as 70 ppm/°C maximum over 0°C to 70°C and 85 ppm/°C over the full −40°C to +85°C range. This makes the ADR510ARTZ-REEL7 suitable for industrial environments, automotive cabin modules, and outdoor portable instrumentation without thermal derating.
