Product details
Overview
The MAX6033AAUT41#TG16 from Maxim Integrated is an ultra-high-precision, low-dropout series voltage reference with 4.096V nominal output, ±0.04% initial accuracy (max), 7ppm/°C max temperature coefficient over –40°C to +125°C, and 40µA quiescent current - designed for high-resolution ADC/DAC biasing in battery-powered instrumentation and industrial control systems.
For engineers reviewing the MAX6033AAUT41#TG16 datasheet, MAX6033AAUT41#TG16 pinout, MAX6033AAUT41#TG16 application, or MAX6033AAUT41#TG16 equivalent, key selection criteria include guaranteed automotive-grade temperature operation, force-sense dual-output architecture for load regulation immunity, low 32µVP-P (0.1Hz–10Hz) noise at 4.096V, and stable performance with capacitive loads up to 100µF.
Technical Context
The MAX6033AAUT41#TG16 implements a bandgap-based series reference topology with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.04% initial accuracy and 7ppm/°C max drift over –40°C to +125°C. Its force-sense (OUTF/OUTS) configuration isolates reference output from load-induced IR drops, enabling <0.002mV/mA load regulation.
It operates from 4.3V to 12.6V input, delivers up to 15mA output current, and maintains stability with output capacitance ranging from 0.1µF to 100µF. Dropout voltage is specified at 0.2V (max) at 1mA load and 0.4V (max) at 10mA across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.04% (±1.64mV) at +25°C - enables direct interface with 12-bit ADCs requiring exact 4.096V full-scale reference. |
| Temp Coefficient | 7ppm/°C max (–40°C to +125°C) - ensures ≤±0.5mV total drift over full automotive temperature range. |
| Quiescent Current | 40µA typical - supports >10-year battery life in portable precision instruments with µA-level system budgets. |
| Noise (0.1–10Hz) | 32µVP-P - contributes <0.008 LSB error in 16-bit 4.096V-range ADCs, preserving effective resolution. |
| Dropout Voltage | 0.2V max at 1mA - allows operation from 4.3V supply while maintaining regulation, critical for low-voltage industrial rails. |
| Load Regulation | 0.002mV/mA max - guarantees <0.03mV shift over 15mA load swing, eliminating need for external buffering in DAC references. |
| Capacitive Load Stability | Stable with 0.1µF to 100µF - accommodates bulk decoupling and long trace routing without oscillation risk. |
Pinout & Package
MAX6033AAUT41#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline), with 1.6mm × 2.9mm footprint and 1.1mm height - optimized for space-constrained PCB layouts in handheld test equipment and sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | I.C. (Internally Connected) | Not externally accessible; internal connection only - must remain unconnected on PCB. |
| 2 | GND | Analog ground reference plane - requires low-impedance connection to system AGND to minimize noise coupling. |
| 4 | IN | Positive supply input - accepts 4.3V to 12.6V; bypass with ≥0.1µF ceramic capacitor placed adjacent to pin. |
| 5 | OUTF | Force output - drives load current; must be shorted to OUTS near device package to maintain regulation accuracy. |
| 6 | OUTS | Sense input - monitors voltage at load point; enables remote sensing to reject trace resistance errors. |
Key Features
| Feature | Design Value |
|---|---|
| Force-sense dual-output architecture | Eliminates voltage drop error from PCB traces or connectors between reference and load, ensuring ±0.04% accuracy at point-of-load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4540BRTZ-R7 | 4.096V output, ±0.02% initial accuracy, 3ppm/°C max drift, but 450µA quiescent current and no force-sense pins. | Higher accuracy and lower drift, but unsuitable for ultra-low-power designs and lacks remote sensing capability. | Select ADR4540BRTZ-R7 only when ultimate drift performance outweighs power budget constraints and trace-length compensation is unnecessary. |
| REF5040AIDR | 4.096V output, ±0.05% initial accuracy, 8ppm/°C max drift, 950µA quiescent current, and no force-sense architecture. | Lower initial accuracy than MAX6033AAUT41#TG16, significantly higher supply current, and no load-regulation immunity. | Choose REF5040AIDR only if TI's qualification ecosystem or existing design reuse justifies trade-offs in power and regulation performance. |
Compared with ADR4540BRTZ-R7 and REF5040AIDR, the MAX6033AAUT41#TG16 uniquely balances ultra-low quiescent current (40µA), force-sense regulation, and automotive-grade drift (7ppm/°C) - making it optimal for battery-powered, high-accuracy, long-trace applications where power and layout flexibility are co-constrained.

FAQ
What is the maximum output current capability of the MAX6033AAUT41#TG16?
The MAX6033AAUT41#TG16 sources up to 15mA of output current while maintaining regulation and specified accuracy. This capability supports direct driving of moderate-current DACs, op-amps, or ADC reference inputs without external buffering - verified across –40°C to +125°C with dropout voltage ≤0.4V at 10mA load.
Does the MAX6033AAUT41#TG16 require an input bypass capacitor?
Yes - a minimum 0.1µF ceramic capacitor placed as close as possible to the IN pin is recommended for optimal line-transient performance. While the MAX6033AAUT41#TG16 can operate without it in static conditions, omitting this capacitor degrades PSRR and increases susceptibility to supply noise, especially during fast input voltage transitions.
How does the force-sense (OUTF/OUTS) configuration improve accuracy in the MAX6033AAUT41#TG16?
The MAX6033AAUT41#TG16 uses OUTF to deliver load current and OUTS to sense voltage at the load point. By shorting these pins near the device and routing OUTS directly to the load, the reference compensates for voltage drop across PCB traces or connectors - ensuring the regulated 4.096V appears precisely at the load, not just at the IC pins.
What is the long-term stability specification for the MAX6033AAUT41#TG16?
The MAX6033AAUT41#TG16 exhibits ≤40ppm long-term stability after 1000 hours of operation - measured as output voltage change under continuous bias at +25°C. This value reflects inherent die-level aging behavior and is independent of temperature cycling or load variations, supporting calibration intervals exceeding 5 years in field-deployed instrumentation.
Can the MAX6033AAUT41#TG16 operate with a 100µF output capacitor?
Yes - the MAX6033AAUT41#TG16 is explicitly characterized and guaranteed stable with output capacitance from 0.1µF up to 100µF. This wide range accommodates both high-frequency ceramic decoupling and bulk electrolytic/tantalum capacitors used in noisy industrial power supplies, without requiring external compensation components.
