Product details
Overview
MAX6033BAUT30#TG16 from Maxim Integrated is an ultra-high-precision series voltage reference with 3.000V nominal output, ±0.20% initial accuracy, 7ppm/°C max temperature coefficient (−40°C to +125°C), 200mV max dropout voltage at 1mA, and 40µA typical quiescent current. It serves as a stable, low-noise reference for high-resolution data converters in automotive-grade industrial systems.
For engineers reviewing the MAX6033BAUT30#TG16 datasheet, MAX6033BAUT30#TG16 pinout, MAX6033BAUT30#TG16 application, or MAX6033BAUT30#TG16 equivalent, key selection criteria include guaranteed automotive temperature operation (−40°C to +125°C), dual-output force/sense architecture for load regulation <0.1mV/mA, stability with up to 100µF capacitive loads, and RoHS-compliant SOT23-6 packaging with top mark AAXM.
Technical Context
The MAX6033BAUT30#TG16 employs bandgap-based series topology with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.20% initial accuracy and 7ppm/°C max tempco over −40°C to +125°C. Its dual-output OUTF/OUTS configuration enables Kelvin sensing to reject PCB trace resistance effects under load.
This device operates from 3.2V to 12.6V input, delivers up to 15mA source current, and maintains 0.002mV/mA typical load regulation (−100µA to +15mA). It achieves 24µVP-P (0.1Hz–10Hz) noise at 3.0V output and settles within 600µs to ±0.01% of final value.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.000V ±0.20% (±6mV) at +25°C - ensures precise DAC/ADC biasing without calibration |
| Tempco | 7ppm/°C max (−40°C to +125°C) - limits drift to ±0.84mV across full automotive range |
| Dropout Voltage | 200mV max at 1mA - enables operation from 3.2V supply with 3.0V output |
| Quiescent Current | 40µA typical - minimizes power draw in battery-powered precision instruments |
| Noise (0.1–10Hz) | 24µVP-P - preserves ENOB in 16-bit+ ADC systems |

| Capacitive Load Stability | Stable with 0.1µF to 100µF - supports robust filtering without oscillation risk |
Pinout & Package
MAX6033BAUT30#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (package code U6F+6, outline 21-0058), with thermal resistance θJA = 134.4°C/W on four-layer board. Pins 1 and 3 are internally connected and must remain unconnected externally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 2 GND | Reference ground return | Low-impedance path for reference current; must be tied to clean analog ground |
| 4 IN | Positive supply input | Accepts 3.2V–12.6V; requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin |
| 5 OUTF | Force output | Delivers regulated 3.0V; connects directly to load and to OUTS via shortest possible trace |
| 6 OUTS | Sense input | Monitors voltage at load; rejects voltage drop across PCB traces and improves load regulation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3330AIDBVR | 3.0V output, ±0.1% initial accuracy, 10ppm/°C max tempco, 180mV dropout, 3.9µA IQ | Lower power but higher tempco and accuracy tolerance; not qualified for automotive temp range | Select for portable, non-automotive applications where ultra-low IQ outweighs tempco and accuracy requirements |

FAQ
What is the maximum input voltage for MAX6033BAUT30#TG16?
The absolute maximum input voltage for MAX6033BAUT30#TG16 is +13V relative to GND. However, the specified operating input range is 3.2V to 12.6V for 3.0V output. Exceeding 12.6V may degrade long-term stability or violate line regulation specs, though the device remains protected up to 13V per absolute maximum ratings.
Does MAX6033BAUT30#TG16 require external capacitors?
Yes, MAX6033BAUT30#TG16 requires a minimum 0.1µF ceramic capacitor between IN and GND for optimal line-transient performance. An output capacitor is not mandatory for stability but is recommended: the device is stable with 0.1µF to 100µF at the OUTF node, and larger values improve transient response in step-load applications.
How does the OUTF/OUTS pin configuration improve accuracy in MAX6033BAUT30#TG16?
The OUTF/OUTS configuration in MAX6033BAUT30#TG16 implements Kelvin sensing: OUTF delivers current to the load, while OUTS senses voltage directly at the load point. This eliminates voltage drop errors across PCB traces and connectors, enabling load regulation of 0.002mV/mA - critical for maintaining accuracy in high-current or long-trace applications.
Is MAX6033BAUT30#TG16 qualified for automotive applications?
Yes, MAX6033BAUT30#TG16 is explicitly rated for the automotive temperature range (−40°C to +125°C) and carries RoHS-compliant packaging (#TG16 suffix). While not AEC-Q200 certified as a standalone component, its guaranteed parametric performance across this range and use in automotive ECUs make it suitable for engine control, ADAS, and infotainment subsystems where full qualification is managed at the module level.
What is the typical turn-on settling time for MAX6033BAUT30#TG16?
MAX6033BAUT30#TG16 settles to within ±0.01% of its final 3.0V output in 600µs under typical conditions (VIN = 5V, COUT = 0.1µF, TA = +25°C). Settling time increases with higher load current or lower input headroom; at minimum dropout (VIN ≈ 3.2V) and 15mA load, it may extend to ~2ms as specified in the datasheet.
