MAX6195CESA+T

Overview

The MAX6195CESA+T is a precision, micropower, low-dropout series-mode voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed nominal output voltage of 5.000V with an initial accuracy of ±25mV and a maximum temperature coefficient of 25ppm/°C. The device operates within a supply voltage range of 5.2V to 12.6V and draws a maximum quiescent supply current of 35µA. It supports source and sink currents up to 500µA with a dropout voltage of 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
• Features internally compensated design ensuring stability with capacitive loads up to 2.2nF
• Offers virtually input-voltage-immune supply current for optimized battery-powered efficiency
• Capable of sourcing and sinking load currents up to 500µA

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 'C' corresponds to the required ±25mV initial accuracy and 25ppm/°C temperature coefficient specifications. Confirm that the '+T' designation indicates tape-and-reel packaging if reel delivery is required. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable operation.

Selection Notes

Select this part when a stable 5V reference is needed with moderate precision requirements. It is suitable for applications where board space is limited due to its small 8-SO package footprint. Consider alternatives from the same family if tighter accuracy or lower temperature coefficients are necessary for the specific system performance.

Part Context

This component belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. These devices share common architectural features including micropower consumption and low-dropout capabilities. The MAX6195 variant specifically targets 5V systems, offering a balance between power efficiency and output stability for general-purpose analog signal conditioning.

Replacement Considerations

Compatible substitutes within the same family include MAX6195BESA+T (±10mV accuracy) and MAX6195AESAT (+/-5mV accuracy). Verify pin compatibility and thermal characteristics before substitution.
