MAX6279 0.1%, 25ppm, Ceramic Shunt Voltage Reference General Description Benefits and Features The MAX6279 is a precision, two-terminal shunt mode, 8-Pin Ceramic Package Reduces System Board Space bandgap voltage reference available in fixed reverse Hermetically Sealed Ceramic Package Offers Stable breakdown voltage of 1.225V. Ideal for space-critical Results vs. Time, Humidity and Temperature applications, the MAX6279 is offered in an 8-Pin ceramic 0.1% (max) Initial Accuracy package. 25ppm/C (max) Temperature Coefficient Guaranteed Laser-trimmed resistors ensure precise initial accuracy. Over -40C to +85C Temperature Range With a 25ppm/C temperature coefficient, the device is offered in three grades of initial accuracy ranging from Wide Operating Current Range: 70A to 12mA 0.1% to 0.5%. The MAX6279 has a 70A to 12mA shunt- Low 28V Output Noise (10Hz to 10kHz) RMS current capability with low-dynamic impedance, ensuring No Output Capacitors Required stable reverse breakdown voltage accuracy over a wide Stable with Capacitive Loads range of operating temperatures and currents. The MAX6279 does not require an external stabilizing capacitor while ensuring stability with capacitive loads. Typical Operating Circuit The MAX6279 is a higher precision device than the LM4040/LM4050.
