MAX6033CAUT41#G16

Overview

The MAX6033CAUT41#G16 is an ultra-high-precision series voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.1% and a maximum temperature coefficient of 40ppm/°C over the -40°C to +125°C automotive temperature range. The device operates within an input voltage range of 4.3V to 12.6V, consuming a typical quiescent supply current of 40µA while sourcing up to 15mA. It features a low dropout voltage of 200mV (max) and utilizes bandgap technology with laser-trimmed thin-film resistors for excellent stability.

Procurement Notes

Verify the specific suffix #G16 against official documentation to confirm RoHS compliance status and lead-free specifications. Confirm package type SOT-23-6 availability and check for any discontinuance notices or lifecycle changes directly from the manufacturer before procurement planning.

Selection Notes

Select this component when a stable 4.096V reference is required in space-constrained designs. The SOT-23-6 package offers a compact footprint compared to larger packages. Ensure the input voltage remains above the minimum dropout threshold to maintain regulation under all load conditions.

Part Context

This part belongs to the MAX6033 family of ultra-high-precision series voltage references. The family includes variants with different output voltages (2.5V, 3V, 4.096V, 5V) and accuracy grades (A, B, C). The 'C' grade denotes ±0.1% initial accuracy, while the 'AUT' suffix indicates automotive temperature rating.

Replacement Considerations

Direct replacements within the same family include MAX6033BAUT41#TG16 (±0.2% accuracy) or MAX6033AAUT41#TG16 (±0.04% accuracy). Verify pin compatibility and thermal characteristics when substituting.
