Frequently Asked Questions
What is the output voltage accuracy of LM4040DIX3-3.0+T and how does it affect ADC calibration?
The LM4040DIX3-3.0+T provides a 3.0V nominal output with 0.1% initial accuracy, meaning the output is guaranteed within 3.0V ±3mV. This level of precision ensures that a 12-bit ADC calibrated against this reference has less than 1 LSB of gain error due to reference inaccuracy under room temperature conditions.
How does the LM4040DIX3-3.0+T perform in battery-powered designs in terms of current consumption?
The LM4040DIX3-3.0+T operates with a minimum reverse current of just 45 µA at the cathode, making it one of the lowest-power shunt references available. This characteristic allows it to run directly from a 3.6V lithium cell with a single resistor, maintaining stable 3.0V output without significantly impacting battery life in portable sensor nodes.
What temperature range does the LM4040DIX3-3.0+T support and what is its temperature coefficient?
The LM4040DIX3-3.0+T operates from -40°C to 125°C, covering both industrial and extended temperature application requirements. Its temperature coefficient is 50 ppm/°C maximum, meaning over a 100°C temperature swing the output shifts by no more than 15mV, which is sufficient for 10-bit to 12-bit ADC reference accuracy.
When would a designer choose LM4040DIX3-3.0+T instead of a series (bandgap) voltage reference?
A designer would choose the LM4040DIX3-3.0+T shunt reference over a series reference when the supply voltage is fixed or tightly regulated, and when circuit simplicity matters more than drop-out voltage. Because shunt references only need a series resistor, they consume fewer components; the 3.0V output and SOT-23-3 package make it ideal for biasing op-amp inputs or setting threshold levels in comparator circuits powered from a 3.3V to 5V rail.
