Product details
Overview
MAX6008AEUR+T from Maxim Integrated is a precision 2.5V two-terminal shunt voltage reference in a 3-pin SOT23 package, featuring 0.2% initial accuracy, 30ppm/°C temperature coefficient, <1µA guaranteed operating current, and operation over -40°C to +85°C. It serves as a low-power, high-precision replacement for LM4040 and LT1004 in battery-powered sensor signal conditioning and portable data acquisition systems.
For engineers reviewing the MAX6008AEUR+T datasheet, MAX6008AEUR+T pinout, MAX6008AEUR+T application, or MAX6008AEUR+T equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance, low thermal drift, and SOT23 footprint compatibility with legacy shunt references.
Technical Context
The MAX6008AEUR+T implements a laser-trimmed bandgap core with on-chip thin-film resistors to achieve 0.2% output voltage accuracy at +25°C. Its two-terminal architecture requires external biasing via a series resistor (RBIAS) to set operating current between 0.5µA and 2mA.
It delivers stable 2.500V ±0.005V reverse breakdown voltage at 1.2µA test current, with dynamic impedance of 2Ω across 1.2µA–2mA, low-frequency noise of 60µVP-P (0.1Hz–10Hz), and thermal hysteresis ≤200ppm after -40°C to +85°C cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.005V at 1.2µA, enabling precise ADC/DAC reference scaling without trimming. |
| Initial Accuracy | ±0.2% at +25°C, reducing system calibration burden in portable instrumentation. |
| Temp Coefficient | ≤30ppm/°C over -40°C to +85°C, limiting full-range drift to ±2.25mV for stable long-term measurements. |
| Operating Current | 0.5µA to 2mA min/max, supporting microamp-level power budgets in coin-cell devices. |
| Dynamic Impedance | 2Ω (1.2µA–2mA), minimizing load-induced voltage shift in varying-current applications. |
| Low-Freq Noise | 60µVP-P (0.1Hz–10Hz), critical for high-resolution 16-bit+ analog front-ends. |
Pinout & Package
MAX6008AEUR+T uses 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 pull-up resistor >2.5V; bypass to GND with ≥0.01µF capacitor for stability. |
| 2 (GND) | Ground Reference | Return path for bias current and load current; must be low-impedance node. |
| 3 (IC) | Internal Test Point | No functional connection required; floating or grounded-no impact on performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed <1µA minimum enables multi-year battery life in wireless sensors. |
| Laser-trimmed accuracy | 0.2% initial tolerance eliminates post-assembly calibration in portable meters. |
| Low thermal drift | 30ppm/°C max ensures <±2.25mV total error across industrial temperature range. |

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 | 0.5% initial accuracy, 100ppm/°C tempco, 60µA min operating current | Higher power consumption and lower accuracy limit use in sub-µA systems | Select when cost sensitivity outweighs ultra-low-current requirements |
| ADR3425ARJZ-R7 | 0.1% initial accuracy, 10ppm/°C tempco, but 300µA min operating current and 5-pin SOT23 package | Not pin-compatible; requires layout change and higher supply current | Choose for highest precision where power budget allows ≥300µA |
Compared with LM4040C25IDBZR and ADR3425ARJZ-R7, the MAX6008AEUR+T uniquely balances sub-1µA operation, 0.2% accuracy, and 3-pin SOT23 compatibility-making it optimal for space-constrained, battery-critical designs where neither legacy nor premium references meet all three criteria simultaneously.

FAQ
What is the guaranteed minimum operating current for MAX6008AEUR+T?
The MAX6008AEUR+T guarantees a minimum operating current of 0.5µA, with typical operation starting at 1.0µA. This ultra-low threshold enables reliable startup and regulation in micro-power systems such as energy-harvesting nodes and coin-cell-powered IoT sensors, where the MAX6008AEUR+T maintains 2.5V output stability even below 1µA.
Does MAX6008AEUR+T require an external capacitor, and if so, what value?
Yes, MAX6008AEUR+T requires a minimum 0.01µF capacitor from OUT to GND for stability. This capacitor suppresses high-frequency oscillation and improves transient response during load or supply step changes. Larger values (e.g., 0.1µF) may further reduce overshoot in fast-switching applications, but the 0.01µF value is sufficient for most precision ADC and DAC reference uses with the MAX6008AEUR+T.
Is MAX6008AEUR+T pin-compatible with LM4040 series shunt references?
No, MAX6008AEUR+T is not pin-compatible with standard LM4040 variants. While both are 3-pin shunt references, MAX6008AEUR+T pin 3 is an internally connected test point (IC), whereas LM4040 pin 3 is typically cathode or anode depending on variant. Direct substitution requires verification of pin function mapping and bias network re-optimization due to differing minimum current and dynamic impedance characteristics of the MAX6008AEUR+T.
What is the maximum reverse current rating for MAX6008AEUR+T?
The MAX6008AEUR+T supports a maximum continuous reverse current of 20mA from OUT to GND. Exceeding this value risks exceeding the 291.73mW power dissipation limit in the SOT23 package at +70°C ambient. For sustained operation, design bias networks to keep current ≤2mA-well within the specified 0.5–2mA operating range-to ensure long-term reliability and thermal stability of the MAX6008AEUR+T.
How does the 30ppm/°C temperature coefficient of MAX6008AEUR+T translate to voltage drift over temperature?
With a 30ppm/°C temperature coefficient, the MAX6008AEUR+T exhibits a maximum voltage drift of ±2.25mV over its full -40°C to +85°C range (125°C span × 30ppm/°C × 2.5V = ±2.25mV). This translates to ±0.09% full-scale error, making the MAX6008AEUR+T suitable for applications demanding stable reference performance without active temperature compensation, such as portable calibration equipment and industrial sensor transmitters.
