MAX6341ESA+T

Overview

The MAX6341ESA+T is a low-noise, precision voltage reference utilizing buried-zener technology to achieve extremely low temperature coefficients and excellent initial accuracy. It provides a fixed 4.096V output with an input voltage range of 8V to 36V. The device supports ±15mA source and sink currents, features optional external trimming and noise reduction capabilities, and operates within a -40°C to +85°C temperature range in an 8-pin SO package.

Feature Summary

• Utilizes buried-zener technology for ultra-low noise performance
• Features industry-standard pinout with optional noise reduction and voltage trim
• Provides stable operation for all capacitive loads from 0µF to 100µF

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• High-accuracy industrial and process control systems
• Digital voltmeters and ATE equipment

Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'E' designation corresponds to the extended -40°C to +85°C operating temperature range required for your application environment. Ensure compatibility with standard 8-pin SOIC footprints during PCB layout.

Selection Notes

Select this component when high stability and low noise are critical for precision measurement applications. Consider the MAX6325 or MAX6350 if alternative fixed output voltages of 2.5V or 5V are needed instead of 4.096V. Evaluate the need for external trimming or noise reduction features based on system sensitivity requirements.

Part Context

This part belongs to the MAX6325/MAX6341/MAX6350 family of 1ppm/°C, low-noise voltage references manufactured by Analog Devices Inc./Maxim Integrated. The series utilizes buried-zener technology to deliver laboratory-standard temperature stability without the power consumption associated with heated references.
