Product details
Overview
The MAX6033CAUT41+T from Maxim Integrated is a precision series voltage reference delivering 4.096V output with ±0.10% initial accuracy, 40ppm/°C max temperature coefficient over –40°C to +125°C, and 200mV max dropout voltage. It sources up to 15mA and consumes only 40µA quiescent current, making it suitable for high-resolution ADC/DAC biasing in automotive-grade industrial instrumentation.
For engineers reviewing the MAX6033CAUT41+T datasheet, MAX6033CAUT41+T pinout, MAX6033CAUT41+T application, or MAX6033CAUT41+T equivalent, key selection criteria include output stability under capacitive loads up to 100µF, low 32µVP-P (0.1Hz–10Hz) noise at 4.096V, and guaranteed operation across the full automotive temperature range.
Technical Context
This device uses laser-trimmed thin-film resistors and post-package trimming to achieve ±0.10% initial accuracy and 40ppm/°C max tempco over –40°C to +125°C. Its bandgap core enables stable performance with capacitive loads up to 100µF and excellent load regulation of 0.002mV/mA (typ) at 4.096V.
The dual-output architecture (OUTF/OUTS) supports remote sensing to reject PCB trace resistance effects, while its 2.7V to 12.6V input range and 40µA supply current enable single-supply operation in battery-powered precision systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum capacitive load the MAX6033CAUT41+T can drive while remaining stable?
The MAX6033CAUT41+T is stable with output capacitance ranging from 0.1µF to 100µF. This wide range eliminates the need for external isolation resistors or ferrite beads in most applications, including those with large bulk decoupling or long PCB traces. Stability is maintained regardless of load current up to 15mA, as confirmed in the datasheet's Applications Information section.
Does the MAX6033CAUT41+T require an input bypass capacitor?
An input bypass capacitor is optional for the MAX6033CAUT41+T but recommended for optimal line-transient performance. A 0.1µF ceramic capacitor placed close to the IN pin reduces sensitivity to supply ripple and improves rejection of fast input transients. The device operates reliably without it when supply quality is high and transient demands are low.
How does the dual-output (OUTF/OUTS) configuration improve accuracy in the MAX6033CAUT41+T?
The MAX6033CAUT41+T uses OUTF to deliver current to the load and OUTS to sense voltage directly at the load point. By shorting OUTF to OUTS near the device and routing OUTS separately to the load, voltage drops across PCB traces are excluded from the feedback loop. This remote sensing preserves output accuracy even with trace resistances up to 1Ω, which is essential for precision DAC/ADC biasing.
What is the typical turn-on settling time for the MAX6033CAUT41+T to reach ±0.01% of final value?
The MAX6033CAUT41+T typically settles to within ±0.01% of its final 4.096V output in 800µs under standard conditions (VIN = 5V, COUT = 0.1µF, TA = +25°C). Settling time increases with heavier capacitive loads or operation near dropout; worst-case is 2ms at minimum input voltage and full 15mA load, as specified in the Typical Operating Characteristics.
Is the MAX6033CAUT41+T qualified for automotive applications?
Yes, the MAX6033CAUT41+T is explicitly rated for the automotive temperature range of –40°C to +125°C and is manufactured in a RoHS-compliant SOT23 package (U6FH+6). Its specifications - including 40ppm/°C tempco, ±0.10% initial accuracy, and 150ppm temperature hysteresis - are guaranteed across this range, satisfying AEC-Q100 stress test expectations for non-automotive-specific qualification.
