Product details
Overview
MAX6006AESA+ from Maxim Integrated is a precision 1.25V two-terminal shunt voltage reference in an 8-pin SO package, featuring 0.2% initial accuracy, 30ppm/°C temperature coefficient over -40°C to +85°C, <1µA guaranteed operating current, and low-frequency noise of 30µVP-P. It serves as a low-power, high-accuracy replacement for legacy references in battery-powered sensor signal chains and portable instrumentation.
For engineers reviewing the MAX6006AESA+ datasheet, MAX6006AESA+ pinout, MAX6006AESA+ application, or MAX6006AESA+ equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance, thermal stability across industrial temperature range, and compatibility with standard 8-pin SO footprint for drop-in upgrades to LT1004-based designs.
Technical Context
The MAX6006AESA+ 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 RBIAS to set reverse current between 1µA and 2mA, enabling operation as a precision shunt regulator or reference node in high-impedance circuits.
Thermal hysteresis is limited to 200ppm, and long-term drift is specified at 150ppm over 1000 hours. The device exhibits reverse dynamic impedance of 1.5Ω (typ) and maintains stable regulation even under load capacitance ≥0.01µF, supporting low-noise ADC/DAC biasing in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | +1.25V nominal; ±0.0025V (0.2%) tolerance at +25°C ensures accurate scaling for 12-bit+ data converters. |
| Initial Accuracy | ±0.2% over full temperature range (-40°C to +85°C); eliminates need for system-level calibration in portable meters. |
| Temp Coefficient | ≤30ppm/°C (Grade A); contributes ≤±2.55mV drift over full range, critical for precision regulators in uncontrolled environments. |
| Operating Current | Guaranteed <1µA minimum; enables multi-year battery life in IoT sensors drawing sub-µA standby current. |
| Low-Freq Noise | 30µVP-P (0.1Hz–10Hz); supports high-resolution analog front-ends without added filtering overhead. |
| Dynamic Impedance | 1.5Ω (typ, 1.2µA–2mA); minimizes output voltage shift under varying load currents in shunt-regulated supplies. |
| Long-Term Drift | 150ppm (1000h @ +25°C); ensures stable reference performance over product lifetime without recalibration. |
Pinout & Package
MAX6006AESA+ uses an 8-pin SO (small outline) package (package code S8+2, outline 21-0041), with thermal resistance θJA = 136°C/W on multilayer board. Pin 1 is OUT, Pin 4 is GND; Pins 1, 2, 3, 5, 7 are N.C., Pin 6 and Pin 8 are also N.C. No internal connection exists for pins marked N.C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | OUT | Reference output terminal; must be biased above GND via external resistor and bypassed with ≥0.01µF capacitor to GND. |
| Pin 4 | GND | Ground reference terminal; provides return path for reverse current and establishes 0V reference for output voltage. |
| Pins 2,3,5,6,7,8 | N.C. | No internal connection; must remain unconnected or tied to GND per design guidelines-no functional impact if left floating. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed <1µA minimum ensures compatibility with energy-harvesting and coin-cell-powered systems. |
| Laser-trimmed accuracy | 0.2% initial tolerance achieved via on-die thin-film resistor trimming-enables single-point calibration elimination. |
| Stable thermal performance | 30ppm/°C max TC over -40°C to +85°C allows use in automotive cabin and industrial field equipment without derating. |
| Low-noise output | 30µVP-P (0.1Hz–10Hz) supports 16-bit+ SAR and delta-sigma ADCs without additional noise filtering. |
| Robust transient response | Settles in 40ms with 10nF cap and 1.2µA bias-enables fast wake-up in duty-cycled sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1004CZ-1.2 | 1.2V output, 0.5% initial accuracy, 50ppm/°C TC, 3-pin TO-92/SOT23; no 8-pin SO option. | Higher TC and lower accuracy limit use in high-precision metering; TO-92 not suitable for automated assembly. | Select when cost sensitivity outweighs accuracy requirements and through-hole assembly is acceptable. |
| LM4040BIM3-1.2 | 1.225V output, 0.2% accuracy, 100ppm/°C TC, 3-pin SOT23 only; higher noise (65µVP-P) and no 8-pin SO variant. | 100ppm/°C TC causes >3× more drift than MAX6006AESA+ over industrial temperature range. | Choose only for legacy SOT23-only layouts where 8-pin SO upgrade is not feasible. |

FAQ
What is the maximum reverse current rating for MAX6006AESA+?
The MAX6006AESA+ supports continuous reverse current up to 20mA, with absolute maximum ratings specifying 20mA forward (GND to OUT) and 20mA reverse (OUT to GND). For reliable long-term operation, the recommended operating range is 1µA to 2mA-ensuring minimal self-heating and optimal voltage stability. Exceeding 2mA may increase drift and reduce accuracy in the MAX6006AESA+.
Does MAX6006AESA+ require an external capacitor, and what value is recommended?
Yes, the MAX6006AESA+ requires an external capacitor from OUT to GND for stability. A minimum of 0.01µF ceramic capacitor is mandatory per the datasheet; larger values (e.g., 0.1µF) improve transient response during load or supply step changes. This capacitor reduces overshoot/undershoot and ensures predictable startup behavior-critical for consistent performance in the MAX6006AESA+.
Can MAX6006AESA+ be used as a direct replacement for LT1004 in 8-pin SO layouts?
Yes, MAX6006AESA+ is explicitly offered as a plug-in upgrade for LT1004 in 8-pin SO packages. Pin 1 (OUT) and Pin 4 (GND) match LT1004's pinout, and all other pins are N.C. The MAX6006AESA+ improves upon LT1004 with tighter 0.2% initial accuracy, lower 30ppm/°C TC, and guaranteed <1µA operation-making it a functional and mechanical upgrade without layout changes.
What is the typical turn-on settling time for MAX6006AESA+?
The MAX6006AESA+ settles within 40ms when biased at 1.2µA with a 10nF output capacitor, as verified in typical operating characteristics. Settling time scales inversely with bias current-e.g., doubling bias current to 2.4µA reduces settling to ~20ms. This behavior is consistent across the MAX6006AESA+ family and supports deterministic wake-up timing in low-power microcontroller applications.
Is MAX6006AESA+ RoHS-compliant and lead-free?
Yes, MAX6006AESA+ is RoHS-compliant and lead-free, indicated by the "+" suffix in its part number per Maxim Integrated's packaging nomenclature. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and supports standard reflow soldering profiles up to +260°C peak temperature-ensuring compatibility with modern high-volume assembly processes for the MAX6006AESA+.
