Frequently Asked Questions
What output voltage does LM4128DQ1MFX1.8/NOPB provide, and over what input range does it remain accurate?
The LM4128DQ1MFX1.8/NOPB delivers a 1.8 V series reference output while accepting input voltages from 2.2 V to 5.5 V. This wide input window allows the device to work from both 3.3 V and 5 V supply rails, making it flexible for mixed-voltage board designs in automotive and industrial applications spanning -40°C to 125°C.
For a 12-bit ADC reference design in an automotive ECU, how suitable is LM4128DQ1MFX1.8/NOPB?
The device is well-suited for 12-bit ADC reference applications in automotive ECUs because it delivers a precise 1.8 V output with micropower quiescent current, fits in a 5-pin SOT-23 package, and meets AEC-Q100 qualification requirements over -40°C to 125°C. The tight initial accuracy prevents significant LSB-level errors in 12-bit conversion chains.
When would LM4128DQ1MFX1.8/NOPB be preferred over a shunt reference in portable battery instruments?
In portable battery instruments where supply voltage may drop below 3.3 V, a series reference like LM4128DQ1MFX1.8/NOPB is preferred because it operates correctly from just 2.2 V input and draws only microamp-level quiescent current, extending battery life. Shunt references typically need more voltage headroom and a dropping resistor that wastes power, making them less efficient in the 2.2 V to 5.5 V range covered by this device.
