Product details
Overview
MAX6007AEUR+T from Maxim Integrated is a precision 2.048V two-terminal shunt voltage reference in a 3-pin SOT23 package, featuring 0.2% initial accuracy, 30ppm/°C temperature coefficient over -40°C to +85°C, <1µA guaranteed operating current, and 50µVP-P low-frequency noise (0.1Hz–10Hz). It serves as a stable voltage reference for high-resolution ADCs and battery-powered instrumentation.
For engineers reviewing the MAX6007AEUR+T datasheet, MAX6007AEUR+T pinout, MAX6007AEUR+T application, or MAX6007AEUR+T equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance, low thermal drift, and compatibility with space-constrained, low-power analog signal chains requiring stable 2.048V reference points.
Technical Context
The MAX6007AEUR+T implements a laser-trimmed series 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 pull-up resistor and 0.01µF minimum output capacitance to GND for stability.
It operates across 1µA–2mA reverse current range with <2.3mV output voltage change from 200µA to 2mA load variation, and exhibits 1.8Ω reverse dynamic impedance (1.2µA–2mA), enabling precise regulation in low-current shunt configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.2% at +25°C - enables exact 12-bit full-scale alignment in 2.048V-referenced ADCs |
| Initial Accuracy | ±0.2% - eliminates need for system-level calibration in portable metering applications |
| Temp Coefficient | ≤30ppm/°C (-40°C to +85°C) - ensures ≤±0.52mV total drift over full industrial temperature range |
| Operating Current | <1µA min guaranteed - supports multi-year operation from coin-cell batteries |
| Low-Freq Noise | 50µVP-P (0.1Hz–10Hz) - minimizes quantization uncertainty in high-resolution data acquisition |
| Dynamic Impedance | 1.8Ω (1.2µA–2mA) - maintains voltage stability under varying load current conditions |
| Long-Term Drift | 150ppm (1000h @ +25°C) - ensures reference stability over product lifetime without recalibration |
Pinout & Package
MAX6007AEUR+T is housed in a RoHS-compliant 3-pin SOT23 package (2.1mm × 2.7mm footprint), optimized for high-density PCB layouts. Pin 1 is OUT, Pin 2 is GND, and Pin 3 is IC (internally connected test point; must be left unconnected or tied to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Reference Output | Bias with external pull-up resistor; bypass to GND with ≥0.01µF capacitor for stability and noise suppression |
| 2 (GND) | Ground Reference | Return path for reference current; must be low-impedance connection to system ground plane |
| 3 (IC) | Internal Test Point | No functional connection; leave floating or connect to GND - no electrical impact on operation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | <1µA minimum ensures >10-year battery life in always-on sensor nodes |
| Laser-trimmed bandgap core | 0.2% initial accuracy achieved via on-die thin-film resistor trimming - no external calibration needed |
| Low thermal hysteresis | <200ppm - prevents memory-effect errors after thermal cycling in field-deployed equipment |
| Wide operating current range | 1µA to 2mA - accommodates variable load currents without output voltage degradation |
| Low-frequency noise performance | 50µVP-P (0.1Hz–10Hz) - preserves effective resolution in slow-sampling precision measurement systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C20IDBZR | 2.048V, ±0.5% initial accuracy, 100ppm/°C TC, 65µVP-P noise, 60µA min operating current | Higher power consumption and lower accuracy limit use in <1µA systems and 12-bit+ ADCs | Select when cost sensitivity outweighs ultra-low current and precision requirements |
| ADR3420ARJZ-R7 | 2.048V, ±0.1% initial accuracy, 10ppm/°C TC, 30µVP-P noise, but 3.5µA min operating current and 5-pin SOT23 package | Superior accuracy/noise but incompatible pinout and higher current prevent drop-in replacement | Select when highest stability is critical and board layout can accommodate 5-pin footprint and higher bias current |
Compared with LM4040C20IDBZR and ADR3420ARJZ-R7, the MAX6007AEUR+T uniquely balances sub-1µA operation, 0.2% accuracy, and 3-pin SOT23 compatibility - making it optimal for space- and energy-constrained designs where neither legacy nor premium alternatives fully satisfy all three constraints simultaneously.

FAQ
What is the guaranteed minimum operating current for MAX6007AEUR+T?
The MAX6007AEUR+T guarantees a minimum operating current of less than 1µA - specifically, IRMIN = 0.5µA to 1.0µA (typical 0.8µA) - ensuring stable 2.048V output even under ultra-low-power conditions. This specification is validated across -40°C to +85°C and allows MAX6007AEUR+T to operate reliably in coin-cell-powered devices with multi-year battery life expectations.
Does MAX6007AEUR+T require an external capacitor, and if so, what value?
Yes, MAX6007AEUR+T requires a minimum 0.01µF capacitor connected between OUT (Pin 1) and GND (Pin 2) to ensure stability and suppress noise. Larger values (e.g., 0.1µF) improve transient response in applications with step-load changes. The capacitor must be placed close to the device pins to minimize parasitic inductance - failure to include this capacitor may cause oscillation or increased low-frequency noise in the MAX6007AEUR+T output.
Can MAX6007AEUR+T be used as a direct replacement for LM4040 in existing designs?
MAX6007AEUR+T shares the same 3-pin SOT23 footprint and pinout as LM4040 variants, but differs in biasing requirements and current range. While it can replace LM4040 in many low-current applications, designers must verify that the external bias resistor (RBIAS) delivers ≥0.5µA but ≤2mA to MAX6007AEUR+T - unlike LM4040's typical 45µA–10mA range. Also, MAX6007AEUR+T's lower noise and tighter TC offer measurable system-level benefits in precision designs.
What is the maximum reverse current rating for MAX6007AEUR+T?
The absolute maximum reverse current for MAX6007AEUR+T is 20mA, as specified in the Absolute Maximum Ratings table. However, the recommended operating range is 1µA to 2mA - exceeding 2mA increases self-heating and degrades long-term drift and temperature coefficient performance. For reliable operation, design RBIAS to limit current to ≤2mA under worst-case supply and load conditions, preserving MAX6007AEUR+T's 30ppm/°C TC and 150ppm 1000-hour drift specifications.
Is MAX6007AEUR+T qualified for automotive applications?
No, MAX6007AEUR+T is not AEC-Q100 qualified. Only the MAX6008AEUR/V+T variant (2.5V version with /V suffix) carries AEC-Q100 qualification. MAX6007AEUR+T is rated for industrial temperature range (-40°C to +85°C) and intended for commercial and industrial applications such as portable test equipment and battery-powered sensors - not under-hood automotive systems requiring extended temperature or reliability validation.
