Product details
Overview
MAX6033AAUT25#TG16 from Maxim Integrated is an ultra-high-precision, low-dropout series voltage reference with 2.500V nominal output, ±0.04% initial accuracy (max), 10ppm/°C max temperature coefficient over –40°C to +125°C, and 40µA quiescent current - designed for high-resolution ADC/DAC biasing in automotive-grade instrumentation and industrial control systems.
For engineers reviewing the MAX6033AAUT25#TG16 datasheet, MAX6033AAUT25#TG16 pinout, MAX6033AAUT25#TG16 application, or MAX6033AAUT25#TG16 equivalent, key selection criteria include guaranteed automotive temperature range operation, force-sense output architecture for load regulation stability, low 16µVP-P (0.1Hz–10Hz) noise, and compatibility with capacitive loads up to 100µF without oscillation.
Technical Context
The MAX6033AAUT25#TG16 employs bandgap-based series topology with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.04% initial accuracy and 10ppm/°C max drift over –40°C to +125°C. Its dual-output force-sense (OUTF/OUTS) architecture isolates reference sensing from load current path, enabling excellent load regulation (0.001mV/mA) and stable operation with large capacitive loads.
This device operates from 2.7V to 12.6V input, delivers up to 15mA output current, and maintains dropout voltage ≤200mV at 1mA load. It features low 16µVP-P noise (0.1Hz–10Hz), 500µs turn-on settling time to ±0.01%, and guaranteed long-term stability of 40ppm over 1000 hours.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.01% (2.4990V to 2.5010V at +25°C) - enables direct interface with 2.5V-rail precision converters without scaling. |
| Initial Accuracy | ±0.04% max at +25°C - reduces system calibration burden in high-accuracy measurement front-ends. |
| Temp Coefficient | 10ppm/°C max over –40°C to +125°C - ensures <±0.3mV total drift across full automotive temperature range. |
| Quiescent Current | 40µA typical - supports ultra-low-power battery-operated instrumentation and sensor nodes. |
| Noise (0.1–10Hz) | 16µVP-P - preserves ENOB in 16-bit+ ADC systems where reference noise dominates quantization error. |
| Dropout Voltage | 200mV max at 1mA - allows operation from 2.7V supply while maintaining 2.5V output, critical for single-supply systems. |
| Load Regulation | 0.001mV/mA - minimizes output shift under dynamic load changes, essential for multiplexed sensor arrays. |
Pinout & Package
The MAX6033AAUT25#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline) with thermal resistance θJA = 134.4°C/W on four-layer board - optimized for space-constrained automotive and industrial PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | Not externally usable; internal connection only - must remain unconnected on PCB. |
| 2 | GND | Analog ground reference plane - requires low-impedance connection to minimize noise coupling into reference node. |
| 4 | IN | Positive power-supply input - accepts 2.7V to 12.6V; bypass with ≥0.1µF ceramic capacitor placed adjacent to pin. |
| 5 | OUTF | Force output - sources load current; must be shorted to OUTS near device and bypassed with ≥0.1µF to GND. |
| 6 | OUTS | Sense input - connects to load-side of OUTF short; provides feedback for precise regulation independent of trace IR drop. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense output architecture | Enables 0.001mV/mA load regulation by separating current delivery (OUTF) from voltage sensing (OUTS), eliminating PCB trace resistance errors. |
| Stable with 100µF capacitive load | Eliminates need for external isolation resistors or ferrite beads in high-capacitance applications like motor drive feedback loops. |
| Ultra-low 16µVP-P noise (0.1–10Hz) | Supports >18-bit effective resolution in precision data acquisition systems without additional filtering. |
| Automotive temperature range | Rated for –40°C to +125°C operation - qualified for under-hood and engine-control module deployment per AEC-Q100 stress requirements. |
| Laser-trimmed thin-film resistors | Delivers ±0.04% initial accuracy without post-assembly calibration, reducing test time and manufacturing cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR3425ARJZ-R7 | 2.5V output, ±0.1% initial accuracy, 15ppm/°C max drift, 12µA quiescent current, SC70-5 package | Lower power but looser accuracy and higher tempco; no force-sense outputs | Select for ultra-low-power portable devices where 0.1% accuracy suffices and layout space is constrained. |
| REF5025IDR | 2.5V output, ±0.05% initial accuracy, 3ppm/°C max drift, 950µA quiescent current, SOIC-8 package | Superior drift performance but 24× higher supply current; includes enable pin and thermal shutdown | Select for lab-grade instrumentation requiring lowest possible drift, accepting higher power and larger footprint. |
Compared with ADR3425ARJZ-R7, MAX6033AAUT25#TG16 trades lower quiescent current for tighter initial accuracy and integrated force-sense architecture; versus REF5025IDR, it sacrifices drift performance for 24× lower supply current and SOT23 space savings - making it optimal for automotive-qualified, medium-accuracy, low-power systems.

FAQ
What is the maximum capacitive load the MAX6033AAUT25#TG16 can drive without instability?
The MAX6033AAUT25#TG16 is stable with capacitive loads up to 100µF, including bypass and load capacitance combined. This eliminates the need for series isolation resistors in applications such as motor drive feedback or high-capacitance ADC reference decoupling. Stability is maintained across the full –40°C to +125°C temperature range and all specified load currents, as verified in the manufacturer's Typical Operating Characteristics plots.
Does the MAX6033AAUT25#TG16 require an input bypass capacitor?
An input bypass capacitor is optional for the MAX6033AAUT25#TG16 but recommended for optimal line-transient performance: a 0.1µF ceramic capacitor placed as close as possible to the IN pin significantly improves rejection of supply ripple and step disturbances. The device remains functional without it when transient response is not critical, per the Applications Information section of the datasheet.
How does the force-sense (OUTF/OUTS) architecture improve accuracy in the MAX6033AAUT25#TG16?
The MAX6033AAUT25#TG16 uses separate OUTF (force) and OUTS (sense) pins to isolate the voltage regulation feedback path from load current conduction. By routing the sense line directly to the load point and keeping OUTF/OUTS shorted near the IC, voltage drops across PCB traces or interconnects do not affect regulation - achieving 0.001mV/mA load regulation and eliminating layout-dependent errors common in single-output references.
What is the guaranteed temperature coefficient specification for MAX6033AAUT25#TG16 over its full operating range?
The MAX6033AAUT25#TG16 guarantees a maximum temperature coefficient of 10ppm/°C over the full automotive operating range of –40°C to +125°C. This value is explicitly specified in the Electrical Characteristics table for the "MAX6033A" grade under "TA = –40°C to +125°C", confirming its suitability for under-hood and industrial environments where thermal stability is critical.
Can the MAX6033AAUT25#TG16 be used in battery-powered applications with supply voltages below 3.0V?
Yes - the MAX6033AAUT25#TG16 operates with a minimum input voltage of 2.7V, enabling use in single-cell Li-ion (2.7–4.2V) or two-cell alkaline (2.7–3.2V) battery systems. Its 200mV max dropout voltage ensures stable 2.500V output even at end-of-discharge, and its 40µA quiescent current minimizes standby power loss, extending operational lifetime in always-on sensor nodes.
