Analog Devices / Maxim Integrated MAX6138 Shunt Voltage Reference
Analog Devices Inc. MAX6138 Shunt Voltage Reference is a precision, two-terminal shunt mode, bandgap voltage reference available in fixed reverse breakdown voltages of 1.2205V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V.
Ideal for space-critical applications, the MAX6138 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount packages. 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 MAX6138 features a 60µA to 15mA shunt-current capability with low-dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. The MAX6138 does not require an external stabilizing capacitor while ensuring stability with capacitive loads.
