Maxim LM4040 Precision Shunt Voltage Reference Datasheet
The LM4040 is an improved precision micropower shunt voltage reference designed for space-critical applications. It offers six fixed reverse breakdown voltages: 2.048V, 2.500V, 3.000V, 3.3V, 4.096V, and 5.000V. The device is available in a subminiature 3-pin SC70 surface-mount package (1.8mm x 1.8mm), which is 50% smaller than comparable SOT23 packages.
Laser-trimmed resistors ensure precise initial accuracy with four grades ranging from 0.1% to 1%. The device features a temperature coefficient of 100ppm/°C and operates over a wide range of -40°C to +125°C. It supports shunt currents from 60µA to 15mA without requiring an external stabilizing capacitor.
