Product details
Overview
The MAX6007BEUR from Maxim Integrated is a precision 2.048V shunt voltage reference in a 3-pin SOT23 package, designed for ultra-low-power, space-constrained systems. It delivers guaranteed initial accuracy of ±0.5%, temperature coefficient of 75ppm/°C over –40°C to +85°C, and minimum operating current <1µA - enabling use in battery-powered meters and portable A/D converters where long-term stability and microamp biasing are critical.
For engineers reviewing the MAX6007BEUR datasheet, MAX6007BEUR pinout, MAX6007BEUR application, or MAX6007BEUR equivalent, this device serves as a direct upgrade path from LM385-2.0 and LT1004-2.0 in low-current, high-accuracy reference designs requiring stable 2.048V output with minimal thermal drift and sub-1µA quiescent operation.
Technical Context
The MAX6007BEUR implements a two-terminal bandgap architecture with on-chip laser-trimmed thin-film resistors to achieve factory-set 2.048V output. Its shunt topology requires external bias current via a pull-up resistor, with operation validated across 1.2µA to 2mA load current range.
It features a reverse dynamic impedance of 1.8Ω (1.2µA–2mA), low-frequency noise of 50µVP-P (0.1Hz–10Hz), and thermal hysteresis ≤200ppm - all specified over the full industrial temperature range without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.5% at +25°C - enables precise scaling in 12-bit ADCs using standard binary reference points. |
| Initial Accuracy | ±0.5% (Grade B) - eliminates need for system-level calibration in portable instrumentation. |
| Temp. Coefficient | 75ppm/°C max (–40°C to +85°C) - contributes ≤±0.15% output error across full industrial range. |
| Min. Operating Current | 1.0µA max - supports operation from microamp-level bias sources such as high-impedance DAC outputs. |
| Dynamic Impedance | 1.8Ω (1.2µA–2mA) - ensures stable regulation under varying load transients in sensor front-ends. |
| Low-Freq. Noise | 50µVP-P (0.1Hz–10Hz) - minimizes quantization uncertainty in high-resolution data acquisition. |
| Long-Term Drift | 150ppm/1000h - supports >5-year field reliability in uncalibrated medical and test equipment. |
Pinout & Package
MAX6007BEUR is housed in a RoHS-compliant 3-pin SOT23 package (2.1mm × 2.7mm), optimized for PCB area-constrained designs. 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 |
|---|---|---|
| OUT (Pin 1) | Reference output node | Bias with external pull-up resistor; must be bypassed to GND with ≥0.01µF capacitor for stability. |
| GND (Pin 2) | Ground reference terminal | Provides return path for shunt current; connects directly to system ground plane for noise immunity. |
| IC (Pin 3) | Internal test point | No functional connection required; floating or grounded - no impact on regulation performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed <1µA minimum - extends battery life in multi-year portable devices without sacrificing accuracy. |
| Laser-trimmed output | Factory-set 2.048V with ±0.5% tolerance - eliminates post-assembly trimming and reduces BOM count. |
| Wide operating current range | 1.2µA to 2mA - accommodates variable load conditions while maintaining <0.2% voltage deviation. |
| Low thermal hysteresis | ≤200ppm - ensures repeatable reference value after thermal cycling in outdoor or automotive environments. |
| Space-saving SOT23 | 2.1mm × 2.7mm footprint - replaces larger SO-8 references (e.g., MAX6008AESA) without layout redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM385B-2.5/NOPB | 2.5V output, ±1% initial accuracy, 100ppm/°C TC, 10µA min operating current | Higher power consumption and lower accuracy limit use in sub-10µA systems and 12+ bit converters | Select when cost sensitivity outweighs precision and ultra-low current requirements |
| LT1004CZ-2.5 | 2.5V output, ±0.5% accuracy, 50ppm/°C TC, 10µA min operating current, SO-8 only | Larger footprint and higher bias current preclude use in coin-cell-powered SOT23 designs | Choose for legacy board upgrades where SO-8 compatibility and tighter TC are prioritized over size and current |
Compared with LM385B-2.5/NOPB and LT1004CZ-2.5, the MAX6007BEUR provides identical accuracy to the latter but in a 75% smaller SOT23 package and with 10× lower minimum operating current - making it uniquely suitable for next-generation ultra-low-power, high-density measurement systems.

FAQ
What is the output voltage tolerance of the MAX6007BEUR over temperature?
The MAX6007BEUR has an initial accuracy of ±0.5% at +25°C and a maximum temperature coefficient of 75ppm/°C across –40°C to +85°C. This results in a total output variation of ≤±0.65% over the full industrial temperature range, verified per the "box method" calculation defined in the datasheet. The MAX6007BEUR maintains this specification without external calibration.
Can the MAX6007BEUR operate with less than 1µA of bias current?
No - the MAX6007BEUR guarantees stable regulation only at operating currents ≥1.0µA, as confirmed by its minimum operating current specification. Below this threshold, output voltage deviates by more than 0.2% from nominal 2.048V. The MAX6007BEUR is not characterized or warranted for sub-microamp operation.
Is a bypass capacitor required for the MAX6007BEUR, and what value is recommended?
Yes - the MAX6007BEUR requires a minimum 0.01µF capacitor between OUT and GND to ensure stability and suppress high-frequency noise. Larger values (e.g., 0.1µF) improve transient response during load or supply step changes. This requirement is explicitly stated in the Applications Information section of the MAX6007BEUR datasheet.
How does the MAX6007BEUR compare to the MAX6007AEUR in terms of performance?
The MAX6007BEUR differs from the MAX6007AEUR solely in grade specification: the 'B' grade offers ±0.5% initial accuracy and 75ppm/°C TC, while the 'A' grade provides ±0.2% accuracy and 30ppm/°C TC. All other parameters - including package, pinout, operating current range, noise, and long-term drift - are identical between MAX6007BEUR and MAX6007AEUR.
What is the maximum power dissipation capability of the MAX6007BEUR in SOT23 package?
The MAX6007BEUR in SOT23 package has a continuous power dissipation rating of 320mW at +70°C, with a thermal derating factor of 4mW/°C above that temperature. At its maximum rated operating current of 2mA and 2.048V output, power dissipation remains below 4.1mW - well within safe limits even at +85°C ambient.
