These figures define the reference's suitability for precision ADC and DAC bias applications where long-term stability matters. ## Shunt reference — load and bias rules As a shunt-type reference, the LM4040AIM3X-5.0 sinks current through its cathode to regulate the output. Maximum output current is 15 mA, and the minimum cathode current is 80 µA.","metaTitle":"LM4040AIM3X-5.0 Shunt Voltage Reference, ±0.1%, 5V, SOT-23-3","metaDescription":"LM4040AIM3X-5.0 precision shunt reference: 5V fixed output, ±0.1% tolerance, 80 µVrms noise, 100ppm/°C drift.
