MAX6241BCSA+

Overview

The MAX6241BCSA+ is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed output of 4.096V with an initial accuracy of ±0.02%. The device features a maximum temperature coefficient of 5ppm/°C and operates within a commercial temperature range of 0°C to +70°C. It accepts an input voltage between 8V and 36V, draws approximately 3.2mA of supply current, and supports source/sink currents up to 15mA. Packaged in an 8-pin SOIC.

Feature Summary

• Buried-zener technology for low noise performance
• External trimming capability via TRIM pin
• Optional noise reduction via NR pin
• Stable operation with capacitive loads

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• High-accuracy industrial process control systems
• Precision digital voltmeters
• Automatic test equipment

Procurement Notes

Verify the specific suffix 'CSA+' corresponds to the 8-pin SO package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the plus sign. Ensure the ordering code matches the required 5ppm/°C temperature coefficient specification for your design requirements.

Selection Notes

Select this component when a fixed 4.096V output is required with high initial accuracy. The B-grade designation indicates a 5ppm/°C temperature coefficient, suitable for commercial applications. Consider the A-grade variant if a tighter 2ppm/°C coefficient is necessary. Verify that the 8-pin SO package footprint fits the PCB layout constraints.

Part Context

Part of the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. The MAX6241 specifically provides a 4.096V output, distinguishing it from the 2.5V MAX6225 and 5V MAX6250 variants. All share identical pinouts and feature sets, differing primarily in output voltage and temperature coefficient grades.
