The ±0.2% initial tolerance and 100 ppm/°C temperature coefficient make it a fit for precision ADC/DAC reference biasing, comparator thresholds, and power-supply monitoring in industrial control, instrumentation, and telecom equipment where a low-cost shunt topology is preferred over a series reference. ## Output range and resistor sizing Because it is a shunt reference, the LM4041BIDBZR behaves like a Zener diode: it requires an external series resistor from the supply to the cathode to set the bias current. The output voltage is programmed with a resistor divider from the cathode to the adjust pin. With a cathode current floor of 80 µA and a maximum output current of 12 mA, the designer sizes the series resistor to keep the total current (load plus reference) within that window across the input voltage range. The 20 µVrms noise over 10 Hz to 10 kHz is low enough for a 12-bit system without additional filtering in most cases. ## Active status, no obsolescence concern It is also ROHS3 Compliant, so it passes EU material restrictions without an exemption expiry.","metaTitle":"Texas Instruments LM4041BIDBZR Shunt Reference","metaDescription":"Texas Instruments LM4041BIDBZR adjustable shunt voltage reference, ±0.2% tolerance, 1.233V to 10V output, SOT-23-3, -40°C to 85°C.
