Analog Devices / Maxim Integrated MAX6279 Precision Ceramic Voltage Reference
Analog Devices MAX6279 Precision Ceramic Voltage Reference is a precision, two-terminal shunt mode, bandgap voltage reference available in a 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 provided in three initial accuracy grades 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 Analog Devices MAX6279 Precision Ceramic Voltage Reference is a higher-precision device than the LM4040/LM4050.
