Frequently Asked Questions
How accurate is the output voltage of the LM4040C25IDCKTG4?
The LM4040C25IDCKTG4 provides a nominal 2.5 V output with a tight tolerance of 2.488 V to 2.512 V, representing approximately ±0.48% accuracy. This level of precision is suitable for ADC reference inputs and analog signal conditioning circuits in automotive and industrial applications.
Can the LM4040C25IDCKTG4 be used in automotive under-hood applications?
Yes, the LM4040C25IDCKTG4 carries an automotive-grade qualification, making it suitable for use in harsh automotive environments. It supports the extended temperature ranges required for under-hood and passenger cabin electronics operating up to 15 mA shunt current.
What is the advantage of a two-terminal shunt reference topology for the LM4040C25IDCKTG4?
A two-terminal shunt reference like the LM4040C25IDCKTG4 requires only a series resistor to set operating current, simplifying the circuit to minimal components. It maintains a regulated 2.5 V across its terminals as long as current stays between its minimum and 15 mA maximum ratings.
How small is the LM4040C25IDCKTG4 package for board space planning?
The LM4040C25IDCKTG4 is housed in a 5-pin SC-70 package, one of the smallest surface-mount transistor-outline packages available. This compact footprint is ideal for designs with tight PCB area constraints, such as wearable devices and densely populated automotive control modules.
