• Features industry-standard pinout with optional noise reduction and voltage trim

Applications

• High-Resolution Analog-to-Digital and Digital-to-Analog Converters
• High-Accuracy Reference Standard
• Digital Voltmeters
• Precision Current Sources

Procurement Notes

Verify the specific suffix 'ESA' corresponds to the -40°C to +85°C operating temperature range and 8-pin SO package. Confirm RoHS compliance status as indicated in ordering information. Ensure the application circuit includes appropriate bypass capacitors on the IN and NR pins to maintain stability and achieve specified noise performance levels.

Selection Notes

Select this component when a stable 4.096V reference is required for 16-bit resolution systems. Consider the MAX6341 over other series members if the specific output voltage matches system requirements. Evaluate the need for external trimming or noise reduction features based on the strictness of the application's accuracy and noise specifications.

Part Context

Part of the MAX6325/MAX6341/MAX6350 family of 1ppm/°C, low-noise voltage references. These devices share identical pinouts and functional characteristics, differing primarily in their fixed output voltages (2.5V, 4.096V, and 5V respectively). The family utilizes low-power temperature-compensation schemes to achieve laboratory-standard stability without heated references.

FAQ

How can the output noise be reduced?

Add a 1µF capacitor to the NR pin to augment wideband noise reduction. Larger values do not improve noise appreciably.

Is the device stable with capacitive loads?

Yes, the MAX6341 is stable with capacitive load values from 0µF to 100µF for all values of load current.
