Product details
Overview
MAX6008BEUR from Maxim Integrated is a precision 2.5V shunt voltage reference in a 3-pin SOT23 package, designed for ultra-low-power operation with guaranteed <1µA minimum operating current, ±0.5% initial accuracy, and 75ppm/°C temperature coefficient over –40°C to +85°C. It serves as a stable voltage reference in battery-powered instrumentation and high-resolution data converters.
For engineers reviewing the MAX6008BEUR datasheet, MAX6008BEUR pinout, MAX6008BEUR application, or MAX6008BEUR equivalent, key selection criteria include its 2.5V output tolerance, sub-1µA bias current capability, SOT23 footprint compatibility, and thermal stability in portable sensing and precision regulation circuits.
Technical Context
The MAX6008BEUR is a two-terminal bandgap-based shunt reference using laser-trimmed thin-film resistors to achieve factory-set 2.5V output. Its operation requires an external pull-up resistor (RBIAS) to establish bias current between supply and OUT, with GND as the reference node and IC pin unconnected.
It delivers stable regulation across 1µA–2mA operating current, exhibits 2.5mV reverse breakdown change from 200µA to 2mA, and maintains low dynamic impedance (2Ω typical) and 60µVP-P low-frequency noise (0.1Hz–10Hz) at 1.2µA bias - enabling high-accuracy analog signal conditioning in space-constrained systems.
Key Specifications

| Initial Accuracy | ±0.5%, specifying maximum deviation before calibration or trimming |
| Temp Coefficient | 75ppm/°C max over –40°C to +85°C, limiting drift-induced error in wide-temperature environments |

| Long-Term Drift | 150ppm over 1000h, defining baseline aging impact on system calibration stability |
Pinout & Package
MAX6008BEUR is housed in a RoHS-compliant 3-pin SOT23 package (2.1mm × 2.7mm), with pin 1 = OUT, pin 2 = GND, pin 3 = IC (internally connected test point; leave unconnected or tie to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Reference output terminal | Bias with external pull-up resistor; bypass to GND with ≥0.01µF capacitor for stability |
| 2 (GND) | Ground reference node | Provides return path for bias and load currents; must be low-impedance connection |
| 3 (IC) | Internal test point | No functional connection required; may be left floating or tied to GND per layout best practice |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C25IDBZR | 2.5V, ±0.5% initial accuracy, 100ppm/°C tempco, 60µA min operating current | Higher quiescent current limits use in sub-µA systems; wider tempco increases drift in extended temperature range | Select when legacy LM4040 footprint compatibility is required and >60µA bias is acceptable |
| ADR3425ARJZ-R7 | 2.5V, ±0.1% initial accuracy, 10ppm/°C tempco, 100µA min operating current | Higher accuracy and lower drift, but 100× higher minimum current precludes ultra-low-power use | Select when long-term stability and precision outweigh ultra-low-current requirements |
Compared with LM4040C25IDBZR and ADR3425ARJZ-R7, the MAX6008BEUR uniquely balances sub-1µA operation, 2.5V output, and ±0.5% accuracy in SOT23 - making it optimal for space- and energy-constrained systems where neither legacy compatibility nor ultra-high precision is primary.

FAQ
What is the guaranteed minimum operating current for MAX6008BEUR?
The MAX6008BEUR guarantees a minimum operating current of 1.0µA typical (0.5µA minimum) to maintain regulation within ±0.2% of its 2.5V output. This ultra-low current threshold allows integration into energy-sensitive designs such as coin-cell-powered sensors and wearable health monitors where every nanoamp matters. The MAX6008BEUR remains functional across 1µA–2mA, offering flexibility in bias resistor selection.
Does MAX6008BEUR require an external capacitor, and if so, what value?
Yes, the MAX6008BEUR requires a minimum 0.01µF capacitor connected between OUT and GND to ensure stability and reduce noise. This capacitor suppresses high-frequency oscillation and improves transient response during load or supply step changes. Larger values (e.g., 0.1µF) may further dampen overshoot in high-dynamic applications, but the 0.01µF value is sufficient for most precision reference uses. No series resistance is needed.
What is the function of the IC pin on MAX6008BEUR?
The IC pin (pin 3) on MAX6008BEUR is an internally connected test point used during wafer probe and final test. It has no functional role in normal operation and must be left unconnected or tied to GND - never driven or loaded. Connecting it to GND does not affect performance and may improve ESD robustness in some layouts. It is not a power, ground, or signal pin.
How does MAX6008BEUR compare to the A-grade version MAX6008AEUR+T?
The MAX6008BEUR differs from MAX6008AEUR+T primarily in initial accuracy (±0.5% vs. ±0.2%) and temperature coefficient (75ppm/°C vs. 30ppm/°C). Both share identical 2.5V nominal output, SOT23 package, and <1µA operating current. The B-grade offers cost-effective performance for applications where tighter thermal drift or higher initial precision is not required - such as general-purpose instrumentation or non-critical sensor biasing.
Can MAX6008BEUR be used as a direct replacement for LM385-2.5 in existing designs?
MAX6008BEUR can replace LM385-2.5 in many cases due to matching 2.5V output and SOT23 footprint, but caution is required: LM385-2.5 typically requires ≥10µA minimum current, whereas MAX6008BEUR operates down to 1µA. Existing bias resistors may overdrive the MAX6008BEUR, risking excess power dissipation. Verify that operating current stays ≤2mA and adjust RBIAS if needed. Thermal performance and long-term drift also differ significantly.
