MAX6192CESA+T

Overview

The MAX6192CESA+T is a precision, micropower, low-dropout voltage reference from the MAX6190–MAX6195/MAX6198 family. 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 of 2.7V to 12.6V, drawing a maximum quiescent current of 35µA. It supports source and sink currents up to 500µA with a dropout voltage of approximately 100mV at full load. The component is housed in an 8-pin SO package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Maintains stable operation with capacitive loads ranging from 0 to 2.2nF without external compensation.
• Features internally compensated design ensuring fast settling times suitable for dynamic applications.

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 that the ordering suffix matches the required specifications, as variations exist within the MAX6192 series regarding accuracy grades (A, B, C). Confirm the package type corresponds to the 8-SO footprint. Ensure the lead-free designation aligns with environmental compliance requirements for the target assembly process. Cross-reference the specific part number against the manufacturer's latest documentation to confirm availability status.

Selection Notes

Select this component when a fixed 2.5V reference is required with moderate precision and low power consumption. The MAX6192 offers a balance between cost and performance, suitable for systems where battery life is critical but ultra-high precision is not mandatory. Consider the 25ppm/°C temperature coefficient and ±10mV initial accuracy against system tolerance requirements before finalizing the design.

Part Context

This device belongs to the MAX6190–MAX6195/MAX6198 series of precision voltage references manufactured by Analog Devices / Maxim Integrated. The series shares common architectural features including micropower operation and low-dropout capabilities. The MAX6192 specifically targets applications requiring a 2.5V output, distinguishing it from other members of the family that provide different fixed voltage levels such as 1.25V or 5.0V.

Replacement Considerations

Direct substitutes within the same family include MAX6192AESA+ and MAX6192BESA+, which offer tighter accuracy and lower temperature coefficients respectively. Verify pin compatibility and electrical parameter alignment when considering these alternatives.
