Frequently Asked Questions
What output voltage accuracy does LM4128DMF-2.0 provide and over what temperature range?
The LM4128DMF-2.0 provides a precise 2.0 V output with 0.1% initial accuracy and a temperature coefficient of 10 ppm/°C. It maintains this stability over the industrial temperature range of -40°C to 125°C, making it reliable for precision measurement and calibration applications.
Which ADC reference designs benefit from using LM4128DMF-2.0 on a 3.3 V rail?
12-bit and 14-bit ADC circuits in data acquisition modules powered from 3.3 V supply benefit from LM4128DMF-2.0 as a 2.0 V reference, as the device operates down to 2.2 V input. Its 0.1% accuracy ensures the ADC's full-scale range error remains within acceptable limits for industrial sensor measurements.
How does the SOT-23-5 package of LM4128DMF-2.0 help in compact PCB design?
The SOT-23-5 package occupies a board area of approximately 3 mm x 1.7 mm, allowing placement adjacent to ADC or DAC ICs without significant routing overhead. This compact footprint supports high-density designs in portable instruments, wearables, and handheld test equipment requiring a stable 2.0 V reference.
When is LM4128DMF-2.0 a suitable alternative to a bandgap reference with external trim?
LM4128DMF-2.0 is preferred when board space is limited and 0.1% output accuracy at 2.0 V is sufficient without trimming. Designs such as 12-bit DAC systems, battery fuel gauges, and portable oscilloscopes avoid external adjustment components by using this factory-trimmed reference in its 5-pin SOT-23-5 package.
