MAX6279

0.1%, 25ppm, Ceramic Shunt Voltage Reference

Hermetically Sealed Ceramic Package Offers Stable Results vs. Time, Humidity and Temperature


Please check latest availability status for a specific part variant.

Description

The MAX6279 is a precision, two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltage of 1.225V. Ideal for space-critical applications, the MAX6279 is offered in an 8-Pin ceramic package.

Laser-trimmed resistors ensure precise initial accuracy. With a 25ppm/°C temperature coefficient, the device is offered in three grades of initial accuracy ranging from 0.1% to 0.5%. The MAX6279 has a 70μA to 12mA shunt current capability with low-dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.

The MAX6279 does not require an external stabilizing capacitor while ensuring stability with capacitive loads. The MAX6279 is a higher precision device than the LM4040/LM4050.
