Product details
Overview
MAX6033CAUT41#TG16 from Maxim Integrated is a high-precision, low-dropout series voltage reference with 4.096V nominal output, ±0.10% initial accuracy, 40ppm/°C max temperature coefficient (–40°C to +125°C), and 40µA quiescent current. It delivers stable reference performance for 16-bit ADCs in automotive-grade industrial instrumentation.
For engineers reviewing the MAX6033CAUT41#TG16 datasheet, MAX6033CAUT41#TG16 pinout, MAX6033CAUT41#TG16 application, or MAX6033CAUT41#TG16 equivalent, key selection criteria include guaranteed 40ppm/°C tempco over full automotive range, 0.2V max dropout at 10mA, stability with up to 100µF capacitive loads, and dual-force/sense output architecture enabling precision remote sensing.
Technical Context
The MAX6033CAUT41#TG16 implements a bandgap-based series voltage reference with laser-trimmed thin-film resistors and post-package trimming for ±0.10% initial accuracy. Its dual-output architecture separates force (OUTF) and sense (OUTS) terminals to eliminate IR drop errors in PCB traces under load.
It operates across 4.3V to 12.6V input range, supports –40°C to +125°C automotive temperature range, and achieves 32µVP-P (0.1Hz–10Hz) output noise-critical for 16-bit data converters requiring 4.096V full-scale reference alignment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADR4540BRZ | 4.096V output, ±0.02% initial accuracy, 3ppm/°C max tempco, 950µA quiescent current | Higher accuracy and lower drift, but 23× higher supply current limits battery use | Select when ultimate precision outweighs power budget constraints |

FAQ
What is the maximum capacitive load the MAX6033CAUT41#TG16 can drive while remaining stable?
The MAX6033CAUT41#TG16 is stable with output capacitive loads ranging from 0.1µF to 100µF. This wide range accommodates both minimal bypassing for space-constrained layouts and large bulk capacitance for improved transient response in noisy power environments. The device's internal compensation eliminates need for external compensation networks.
How does the dual-output (OUTF/OUTS) architecture of the MAX6033CAUT41#TG16 improve reference accuracy?
The MAX6033CAUT41#TG16 uses separate force (OUTF) and sense (OUTS) outputs to eliminate voltage drop errors caused by PCB trace resistance between the reference IC and load. By routing the sense line directly to the load point, the internal amplifier adjusts OUTF to maintain precise 4.096V at the load-even with trace resistances up to 1Ω-enabling true Kelvin sensing in compact layouts.
What is the minimum input voltage required for the MAX6033CAUT41#TG16 to maintain regulation at 10mA load?
The MAX6033CAUT41#TG16 requires a minimum input voltage of 4.296V to maintain regulation at 10mA load, calculated as VOUT + VDO = 4.096V + 0.2V. This 4.3V minimum input enables reliable operation from standard 4.5V auxiliary rails in automotive and industrial systems, with 200mV headroom for supply tolerance and ripple.
Does the MAX6033CAUT41#TG16 require an input bypass capacitor?
An input bypass capacitor is optional for the MAX6033CAUT41#TG16 but recommended for optimal line-transient performance. A 0.1µF ceramic capacitor placed close to the IN pin reduces sensitivity to supply noise and improves rejection of fast input transients. Without it, the device remains functional but exhibits higher PSRR above 1kHz.
What is the long-term stability specification for the MAX6033CAUT41#TG16, and how is it measured?
The MAX6033CAUT41#TG16 exhibits 40ppm long-term stability after 1000 hours of operation at +125°C. This value represents the maximum change in output voltage observed under accelerated life testing conditions and reflects the combined effects of die stress relaxation and resistor aging-providing a realistic projection of drift in field-deployed systems over multi-year service life.
