MAX6195CESA+

Overview

The MAX6195CESA+ is a precision, micropower, low-dropout series-mode voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 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 200mV at full load. The component is housed in an 8-pin SO package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'CESA+' against official documentation to confirm lead-free/RoHS compliance status and exact tolerance grade. Ensure the input voltage source can provide sufficient transient current during turn-on to guarantee reliable operation. Confirm that the required output accuracy aligns with the C-grade specifications provided in the datasheet electrical characteristics tables.

Selection Notes

Select this component when a fixed 5V reference is required with moderate precision and low power consumption. The MAX6195 family is suitable for applications where board space is limited due to optional output capacitance requirements. Consider the 25ppm/°C temperature coefficient and ±25mV initial accuracy limits to ensure they meet system error budgets compared to higher-precision A or B grades.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references. The family shares common architectural features including micropower operation and low-dropout capabilities. Variants within the series differ primarily in output voltage levels (ranging from 1.25V to 5.0V) and accuracy grades (A, B, C), allowing designers to choose specific performance tiers while maintaining consistent interface and pinout characteristics.

Replacement Considerations

Other members of the MAX619x family, such as MAX6195BESA+ or MAX6195AESAT+, offer different accuracy grades but maintain the same 5.0V output and pin configuration.
