MAX6035ESA25+T

Overview

The MAX6035ESA25+T is a high-voltage, precision micropower voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 40ppm/°C across the -40°C to +85°C range. The device operates within a supply voltage range of 4.4V to 33V, drawing a typical quiescent current of 73µA. It features a source current capability of 10mA and a sink current of 2mA. Packaged in an 8-pin SOIC, it is specified for industrial temperatures.

Feature Summary

• Offers high-precision performance with laser-trimmed thin-film resistors and proprietary curvature-correction circuitry.
• Eliminates the need for external compensation capacitors while remaining stable with capacitive loads up to 5µF.
• Provides supply-independent operation that minimizes power waste compared to conventional shunt-mode references.

Applications

• 12-Bit A/D and D/A Converters
• Digital Multimeters
• Portable Data-Acquisition Systems

Procurement Notes

Verify the specific suffix 'ESA' indicates the 8-pin SO package and the '-25' designates the 2.5V output variant. Confirm the '+T' suffix aligns with your required tape-and-reel packaging specifications. Ensure the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer's latest datasheet revision to validate electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when an 8-pin SO package is preferred over the SOT23 form factor. Choose the ESA variant specifically for applications restricted to the -40°C to +85°C temperature range. This part is suitable for designs requiring higher input voltages up to 33V without external biasing resistors. Consider the 40ppm/°C temperature coefficient limit when designing for wide thermal excursions beyond standard industrial ranges.

Part Context

This component belongs to the MAX6035 family of high-supply-voltage precision voltage references. It serves as a direct upgrade for industry-standard devices like the REF02 and REF43, offering significantly lower power consumption and reduced physical footprint. The family includes variants in both SOT23 and SO packages with different output voltages and accuracy grades.
