Product details
Overview
MAX6007AEUR-T from Maxim Integrated is a precision 2.048V two-terminal shunt voltage reference in a 3-pin SOT23 package, guaranteed initial accuracy of ±0.2%, temperature coefficient ≤30ppm/°C over –40°C to +85°C, and ultra-low operating current <1µA. It serves as a stable reference for high-resolution ADCs, portable battery-powered meters, and low-power precision regulators.
For engineers reviewing the MAX6007AEUR-T datasheet, MAX6007AEUR-T pinout, MAX6007AEUR-T application, or MAX6007AEUR-T equivalent, key selection criteria include its 2.048V output (ideal for 12-bit DAC/ADC full-scale alignment), sub-1µA minimum operating current, 30ppm/°C tempco, SOT23 footprint compatibility, and direct upgrade path from LM4040B20/LT1004-2.048.
Technical Context
The MAX6007AEUR-T implements a laser-trimmed series bandgap core with on-chip thin-film resistors, delivering factory-calibrated 2.048V output. Its two-terminal architecture requires external biasing via a pull-up resistor and mandates ≥0.01µF bypass capacitance from OUT to GND for stability.
It operates across 1.2µA–2mA reverse current, exhibits ≤2.3mV voltage shift from 200µA to 2mA load change, and maintains ≤1.8Ω dynamic impedance over that range. Thermal hysteresis is specified at ≤200ppm after –40°C to +85°C cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048V ±0.2% (min/max = 2.0439V/2.0521V at +25°C); matches 12-bit full-scale binary step for precise data converter referencing. |
| Initial Accuracy | ±0.2% (Grade A); eliminates need for system-level calibration in portable instrumentation. |
| Tempco | ≤30ppm/°C (–40°C to +85°C); ensures <±0.52mV drift over full industrial range, critical for unregulated battery supplies. |
| Min Operating Current | 1.0µA max (IRMIN); enables operation from microampere-level bias networks in energy-harvesting sensors. |
| Dynamic Impedance | 1.8Ω (1.2µA–2mA); minimizes load-induced voltage sag during transient current demands in precision analog front-ends. |
| Low-Freq Noise | 50µVP-P (0.1Hz–10Hz); supports high-resolution DC measurements without added filtering overhead. |
| Long-Term Drift | 150ppm (1000h @ +25°C); ensures reference stability over product lifetime in sealed medical devices. |
Pinout & Package
MAX6007AEUR-T uses a 3-pin SOT23 package (2.1mm × 2.7mm footprint) with JEDEC MO-178AC outline. Pin 1 is OUT, Pin 2 is GND, Pin 3 is 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; must be bypassed to GND with ≥0.01µF capacitor for stability and noise suppression. |
| 2 (GND) | Ground reference node | Provides return path for reverse current; connects to system ground plane to minimize noise coupling into reference node. |
| 3 (IC) | Internal test point | No functional connection required; floating or grounded-no impact on electrical performance per datasheet specification. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed <1µA minimum operating current enables use in coin-cell-powered IoT sensors with >10-year battery life. |
| Laser-trimmed bandgap core | 0.2% initial accuracy achieved via on-die thin-film resistor trimming-eliminates post-assembly calibration in production test. |
| 2.048V output voltage | Exact match to 211 mV; simplifies full-scale scaling in 12-bit SAR ADCs and digital potentiometer interfaces without gain adjustment. |
| 30ppm/°C tempco (Grade A) | Specified over –40°C to +85°C industrial range-ensures consistent performance in automotive cabin modules and outdoor metering. |

|---|---|---|---|
| LM4040B20IDCKR | 2.048V, ±0.2% initial accuracy, 100ppm/°C tempco (–40°C to +85°C), 65µA min operating current. | Higher tempco and quiescent current limit use in high-precision, ultra-low-power systems. | Select when cost sensitivity outweighs tempco and current requirements; verify layout for higher dynamic impedance (15Ω). |
| LT1004CZ-2.5#TRMPBF | 2.5V output, ±0.5% initial accuracy, 50ppm/°C tempco, 10µA min operating current; no 2.048V variant available. | Requires external resistor divider to scale 2.5V to 2.048V, adding error sources and board area. | Choose only if existing design already uses LT1004 family and 2.5V-to-2.048V scaling is acceptable; not drop-in compatible. |

FAQ
What is the guaranteed minimum operating current for MAX6007AEUR-T?
The MAX6007AEUR-T guarantees a maximum minimum operating current (IRMIN) of 1.0µA, defined as the lowest reverse current at which the output voltage deviates by less than 0.2% from its value at 1.2µA. This enables reliable startup and regulation in micro-power sensor nodes where bias current is tightly constrained.
Can MAX6007AEUR-T be used without an external bypass capacitor?
No-MAX6007AEUR-T requires a minimum 0.01µF capacitor from OUT to GND for stability, as explicitly mandated in the Applications Information section. Omitting this capacitor risks oscillation, increased noise, and degraded transient response, especially under load or supply step changes.
Is MAX6007AEUR-T pin-compatible with other parts in the MAX6006–MAX6009 family?
Yes-MAX6007AEUR-T shares identical 3-pin SOT23 pinout (OUT, GND, IC) with all SOT23-packaged variants in the MAX6006–MAX6009 family, including MAX6006AEUR-T, MAX6008AEUR-T, and MAX6009AEUR-T. This allows voltage-scaling flexibility within the same PCB footprint.
What is the thermal hysteresis specification for MAX6007AEUR-T?
MAX6007AEUR-T has a thermal hysteresis of ≤200ppm, measured as the change in output voltage at +25°C before and after cycling between –40°C and +85°C. This low hysteresis ensures repeatable reference performance in cyclic environmental conditions such as outdoor metering or automotive cabin modules.
Does MAX6007AEUR-T support operation at supply voltages below 2.048V?
No-MAX6007AEUR-T is a shunt reference and requires the bias voltage applied to OUT (via RBIAS) to exceed 2.048V to maintain reverse breakdown conduction. Operation below 2.048V places it outside regulation, resulting in uncontrolled leakage current and undefined output voltage.
