MAX6241ACSA+

Overview

The MAX6241ACSA+ is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed output of 4.096V with ±0.02% initial accuracy and a maximum temperature coefficient of 2.0ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. Designed for the commercial temperature range of 0°C to +70°C, it features optional noise reduction and external trimming capabilities.

Feature Summary

• Buried-zener technology ensures extremely low noise performance and high stability.
• Offers industry-standard pinout with optional external trimming and noise reduction.
• Capable of sourcing and sinking load currents up to 15mA with excellent regulation.

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• High-accuracy industrial process control systems
• Precision current sources

Procurement Notes

Verify the specific suffix 'CSA+' indicates the SOIC package and RoHS compliance. Confirm the 'A' grade meets the required 2.0ppm/°C temperature coefficient limit. Ensure the operating environment remains within the specified 0°C to +70°C range to maintain guaranteed electrical characteristics.

Selection Notes

Select this component when a fixed 4.096V reference is required for high-resolution data conversion systems. Consider the buried-zener architecture for superior noise performance compared to standard bandgap references. Evaluate the need for external trimming if tighter tolerance than ±0.02% is necessary.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While sharing identical architectural features and pinouts, the MAX6241 variant is specifically factory-trimmed for a 4.096V output, distinguishing it from the 2.5V and 5.0V counterparts in the series.

Replacement Considerations

Direct functional replacements include other MAX6241 variants such as MAX6241AEPA+ or MAX6241AMJA, provided the package type and extended temperature ranges align with system requirements.

FAQ

How can the output noise be reduced?

Connect a 1μF capacitor between the NR (Noise Reduction) pin and ground to augment wideband noise reduction.

Is the device stable with capacitive loads?

Yes, the MAX6241ACSA+ is stable with capacitive load values ranging from 0μF to 100μF across all load currents.
