Product details
Overview
MAX6033BAUT41#TG16 from Maxim Integrated is a high-precision, low-dropout series voltage reference with 4.096V nominal output, ±0.20% initial accuracy (max), 15ppm/°C max temperature coefficient over -40°C to +125°C, and 40µA quiescent current. It delivers stable 15mA output current and supports capacitive loads up to 100µF, making it suitable for high-resolution 12-bit to 16-bit ADC/DAC biasing in automotive-grade instrumentation.
For engineers reviewing the MAX6033BAUT41#TG16 datasheet, MAX6033BAUT41#TG16 pinout, MAX6033BAUT41#TG16 application, or MAX6033BAUT41#TG16 equivalent, key selection considerations include its 4.096V output alignment with standard 12-bit DAC full-scale ranges, automotive temperature qualification, low-noise performance (32µVP-P, 0.1Hz–10Hz), and dual-output force/sense architecture for precision load regulation.
Technical Context
The MAX6033BAUT41#TG16 employs bandgap-based series topology with laser-trimmed thin-film resistors and post-package trimming to achieve ±0.20% initial accuracy and 15ppm/°C tempco over -40°C to +125°C. Its dual-output structure separates force (OUTF) and sense (OUTS) paths to eliminate IR drop errors under load.
It operates from 4.3V to 12.6V input, maintains 0.2V max dropout at 1mA, and delivers 0.002mV/mA load regulation (typ) - enabling stable reference generation even with varying DAC sink currents or PCB trace resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 4.096V ±0.20% (±8.2mV) at +25°C - matches standard 12-bit DAC full-scale code resolution. |
| Tempco | 15ppm/°C max (-40°C to +125°C) - contributes ≤±0.75mV drift across full automotive range. |
| Quiescent Current | 40µA typ - enables multi-year battery life in portable precision instruments. |
| Noise (0.1–10Hz) | 32µVP-P - limits quantization uncertainty to <0.008 LSB in 16-bit 4.096V systems. |
| Dropout Voltage | 0.2V max at 1mA - allows operation from 4.3V supply, compatible with 5V or 3.3V LDO rails. |
| Load Regulation | 0.002mV/mA typ - ensures <±0.03mV shift across 15mA output range, critical for ratiometric ADCs. |
| Capacitive Load Stability | Stable with 0.1µF to 100µF - accommodates bulk decoupling without oscillation risk. |
Pinout & Package
MAX6033BAUT41#TG16 is housed in a RoHS-compliant 6-pin SOT23 package (U6F+6 outline) with 1.6mm × 2.9mm footprint and 0.95mm height, rated for -40°C to +125°C operation.
| 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; requires low-impedance connection to system AGND plane. |
| 4 | IN | Positive supply input (4.3V–12.6V); bypass with ≥0.1µF ceramic capacitor near pin. |
| 5 | OUTF | Force output - drives load; connect directly to OUTS via shortest possible trace. |
| 6 | OUTS | Sense input - monitors reference node voltage; connects to precision load or ADC REF pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output force/sense architecture | Eliminates voltage drop error from PCB traces or load current, preserving reference 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 |
|---|---|---|---|
| REF3440RTET | 4.096V output, ±0.05% initial accuracy, 6ppm/°C max tempco, 85µA IQ, SOT23-6 | Higher accuracy and lower tempco, but 2.1× higher quiescent current limits battery life | Select when absolute initial accuracy dominates power budget constraints |

FAQ
What is the output voltage tolerance of MAX6033BAUT41#TG16 at +25°C?
The MAX6033BAUT41#TG16 has an output voltage of 4.096V with ±0.20% initial accuracy at +25°C, corresponding to a guaranteed range of 4.0878V to 4.1042V. This tolerance is laser-trimmed and specified in the Electrical Characteristics table for the B-grade variant under TA = +25°C conditions.
Does MAX6033BAUT41#TG16 require external capacitors for stability?
Yes, MAX6033BAUT41#TG16 requires a minimum 0.1µF ceramic capacitor on the IN pin for optimal line-transient performance, and it is stable with output capacitive loads from 0.1µF up to 100µF. The device's dual-output architecture (OUTF/OUTS) mandates short, low-inductance routing between these pins to maintain regulation accuracy.
What is the maximum operating temperature range for MAX6033BAUT41#TG16?
MAX6033BAUT41#TG16 is qualified for continuous operation from -40°C to +125°C, meeting automotive-grade environmental requirements. Absolute maximum junction temperature is +150°C, and thermal resistance (θJA) is 134.4°C/W on a four-layer board per JEDEC JESD51-7.
How does the force/sense (OUTF/OUTS) configuration improve accuracy in MAX6033BAUT41#TG16?
The OUTF/OUTS configuration in MAX6033BAUT41#TG16 separates the current-driving path (OUTF) from the voltage-sensing path (OUTS), eliminating voltage drop errors caused by PCB trace resistance or load current. This ensures the sensed reference voltage remains accurate at the point of use - critical for high-precision ADCs and DACs.
Can MAX6033BAUT41#TG16 be used with a 3.3V supply rail?
No - MAX6033BAUT41#TG16 requires a minimum input voltage of 4.3V (per Electrical Characteristics for VOUT = 4.096V). A 3.3V rail falls below this threshold and cannot sustain regulation. A 5V or higher supply is required; dropout is 0.2V max at 1mA, so 4.3V is the practical lower limit.
