MAX6192CESA+

Overview

The MAX6192CESA+ is a precision, micropower, low-dropout series-mode voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.5V with an initial accuracy of ±10mV and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range from VOUT + 0.2V to 12.6V and draws a maximum quiescent supply current of 35µA. It supports source and sink currents up to 500µA while maintaining stability with capacitive loads up to 2.2nF.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Features internally compensated design ensuring fast settling times without external components
• Offers virtually constant supply current independent of input voltage variations

Applications

• Hand-Held Instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'CESA+' against the manufacturer's official documentation to confirm lead-free/RoHS compliance and package type. Ensure the ordering code matches the required initial accuracy grade (±10mV) and temperature coefficient (25ppm/°C). Confirm availability status directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate precision and low power consumption. It is suitable for battery-powered applications due to its micropower characteristics and low dropout voltage. Consider alternative grades if tighter accuracy or lower temperature coefficients are necessary for the specific application requirements.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. The family shares common architectural features including low dropout operation and micropower consumption. Variations within the family differ primarily in output voltage, initial accuracy, and temperature coefficient specifications, allowing designers to choose the optimal balance between performance and cost.

Replacement Considerations

Compatible substitutes within the same family include MAX6192AESA+ (±2mV accuracy) and MAX6192BESA+ (±5mV accuracy), which offer higher precision at the same 2.5V output. These parts share identical pinouts and electrical characteristics except for accuracy and temperature coefficient specs.
