LM4040B33QFTA DIODES Voltage References

The LM4040B33QFTA is an AEC-Q101 qualified precision micropower shunt voltage reference from Diodes Incorporated, providing fixed 3.3V output with ±0.2% initial accuracy for automotive and industrial applications. For selection, verify fixed 3.3V reference voltage, 60µA to 15mA operating current range, initial accuracy of ±0.2% (B grade), low dynamic impedance, wide operating current range, and -40°C to +125°C operating temperature with AEC-Q101 qualification. Features include no output capacitor required, stable with all capacitive loads, low temperature coefficient, and ESD protection. Ideal for automotive electronics (sensor interfaces, battery management), precision power supplies, data acquisition systems (ADCs/DACs), portable instrumentation, and any high-accuracy voltage reference application requiring 3.3V with automotive-grade reliability.
