MAX6241AEPA+

Overview

The MAX6241AEPA+ is a buried-zener voltage reference providing a fixed 4.096V output in an 8-pin PDIP package. It operates within an extended temperature range of -40°C to +85°C and accepts input voltages from 8V to 36V. The device features ±0.02% initial accuracy, a maximum temperature coefficient of 3.0ppm/°C, and low noise performance of 2.4µVP-P (0.1Hz to 10Hz). It supports continuous source and sink currents up to 15mA with a typical supply current of 3.2mA.

Feature Summary

• Utilizes buried-zener technology for superior noise reduction and stability
• Offers optional external trimming and noise reduction capabilities via dedicated pins
• Maintains stability across all capacitive loads without oscillation
• Provides excellent transient response and long-term drift characteristics

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• High-accuracy industrial and process control systems
• Digital voltmeters and high-accuracy reference standards
• Automated test equipment (ATE)
• Precision current sources

Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C operating range and 'A' indicates the tighter 3.0ppm/°C temperature coefficient limit. Confirm the '+' suffix denotes lead-free/RoHS compliance. Check manufacturer discontinuance notifications as availability may be restricted or limited.

Selection Notes

Select this component when precise 4.096V referencing is required for high-resolution data conversion systems. Ensure the input voltage remains between 8V and 36V. Consider the optional trim pin if fine-tuning is necessary, and utilize the NR pin for applications demanding minimal wideband noise.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise precision voltage references. While sharing identical pinouts and core technologies, 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.
