Product details
Overview
ADR510ARTZ-R2 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 μVp-p (0.1 Hz to 10 Hz) output noise, and stable operation from 100 μA to 10 mA. It enables high-accuracy voltage referencing in space-constrained, battery-powered precision data acquisition systems.
For engineers reviewing the ADR510ARTZ-R2 datasheet, ADR510ARTZ-R2 pinout, ADR510ARTZ-R2 application, or ADR510ARTZ-R2 equivalent, key selection criteria include low-noise performance, trim capability via TRIM/NC terminal, no external capacitor requirement, and compatibility with portable medical instruments and 8-/12-bit data converters requiring stable 1.0 V reference.
Technical Context
The ADR510ARTZ-R2 operates as a two-terminal shunt reference, requiring an external bias resistor to set operating current between 100 μA and 10 mA. Its internal bandgap architecture achieves ultralow thermal hysteresis (50 ppm) and maintains stability across capacitive loads without mandatory output capacitance.
It features a dedicated TRIM/NC terminal enabling ±0.5% output voltage adjustment without degrading temperature coefficient, and supports both positive (1.0 V) and negative (−1.0 V) reference configurations using standard op-amp or passive biasing topologies.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLVH431AIDBZR | 2.5 V nominal output; ±0.5% initial accuracy; 100 ppm/°C tempco; requires external capacitor for stability | Not suitable for 1.0 V systems; higher voltage headroom needed; less noise-sensitive designs | Select only if system uses 2.5 V reference and can accommodate higher drift and noise |
| MAX6126AASA+T | 1.25 V output; ±0.06% initial accuracy; 3 ppm/°C tempco; series topology; requires 2.7 V min supply | Higher accuracy but incompatible pinout and topology; needs ≥2.7 V supply; not shunt-based | Choose only when ultra-low drift is critical and supply voltage allows series regulator operation |

FAQ
What is the output voltage tolerance of the ADR510ARTZ-R2 at 25°C?
The ADR510ARTZ-R2 has an initial output voltage tolerance of ±3.5 mV (±0.35%) at 25°C, corresponding to a guaranteed range of 0.9965 V to 1.0035 V. This specification is tested and guaranteed per the ADR510 Rev. B datasheet, Table 2, and applies to all units shipped in the ADR510ARTZ-R2 ordering variant.
Does the ADR510ARTZ-R2 require an external capacitor for stability?
No, the ADR510ARTZ-R2 does not require an external capacitor for stability. Its advanced shunt design ensures unconditional stability with any capacitive load, eliminating the need for output bypass capacitors. This simplifies layout and reduces BOM count-confirmed in the General Description and Applications Information sections of the ADR510 Rev. B datasheet.
Can the ADR510ARTZ-R2 be used to generate a negative reference voltage?
Yes, the ADR510ARTZ-R2 can generate a precise −1.0 V reference by connecting its V+ terminal to system ground and its V− terminal to −VDD, leveraging its shunt diode-like behavior. Figure 14 in the ADR510 Rev. B datasheet explicitly validates this configuration, and the device maintains its 70 ppm/°C tempco and 4 μVp-p noise performance in this mode.
What is the function of the TRIM/NC pin on the ADR510ARTZ-R2?
On the ADR510ARTZ-R2, the TRIM/NC pin (Pin 3) enables ±0.5% output voltage adjustment using an external potentiometer-without affecting temperature coefficient. When unused, it must remain unconnected (NC). This feature allows system-level trimming to correct for PCB-level errors, as detailed in Figure 12 and the Output Voltage Trim section of the ADR510 Rev. B datasheet.
What is the minimum operating current for the ADR510ARTZ-R2 across its full temperature range?
The ADR510ARTZ-R2 guarantees stable operation down to 100 μA minimum current over 0°C to 70°C, and remains functional at 100 μA across its full −40°C to +85°C range. This low current threshold enables multi-year operation in battery-powered devices, as specified in Table 2 (Electrical Characteristics) and General Description of the ADR510 Rev. B datasheet.
