MAX6008BESA+

Overview

The MAX6008BESA+ is a precision shunt voltage reference offering a nominal output of +2.5V in an 8-pin SO package. It belongs to the MAX6006–MAX6009 family, designed for space-critical and low-power applications with a minimum operating current guaranteed below 1µA. The device features an initial accuracy of 0.2% and a maximum temperature coefficient of 30ppm/°C over the extended temperature range of -40°C to +85°C. Factory-trimmed output voltages include +1.25V, +2.048V, +2.5V, and +3.0V.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and compliance status. The plus sign indicates lead-free and RoHS-compliant packaging. Confirm that the selected variant matches the required initial accuracy and temperature coefficient specifications for the intended application environment.

Selection Notes

Select this component when ultra-low power consumption and high precision are critical requirements. The 8-pin SO package provides a suitable alternative for applications requiring higher pin counts or different thermal characteristics compared to the SOT23 version. Ensure the bias resistor is sized correctly to maintain operation within the specified current range under all supply and load conditions.

Part Context

This part is part of the MAX6006–MAX6009 series of ultra-low-power shunt references. These devices serve as lower-power, higher-precision upgrades to legacy references such as the ICL8069, LM385, LT1004, and LM4040. The series utilizes BiCMOS process technology with laser-trimmed thin-film resistors to achieve precise output voltages.

Replacement Considerations

The datasheet identifies the MAX6008 as a direct upgrade replacement for the LT1004 and LM285 references.
