What are the key features of LM4040AIM3-3.0+?
- 0.1% initial accuracy (A-grade) delivers precise 3.0 V reference for 12-bit and 16-bit ADC and DAC calibration
- Shunt (parallel) topology works from 2.5 V to 18 V supply without a dedicated regulated input rail
- Ultra-compact 3-pin SOT-23 package occupies minimal PCB area in portable and space-constrained designs
- Low temperature coefficient minimizes reference drift over industrial –40°C to 125°C temperature ranges
- No external capacitors required for stability, simplifying BOM and PCB layout in high-volume production
What is LM4040AIM3-3.0+ used for?
The LM4040AIM3-3.0+ provides a stable 3.0 V reference for analog-to-digital and digital-to-analog converters in precision measurement instruments, portable medical devices, and industrial sensors where a clean reference voltage improves conversion accuracy. Its shunt topology and wide supply range (2.5 V–18 V) allow it to be powered directly from the system supply through a single resistor, eliminating a series LDO in space-constrained nodes. The 3-pin SOT-23 footprint and 0.1% accuracy grade make it a low-cost choice for battery-operated data loggers, calibration circuits, and analog front-end voltage dividers.
