Precision 4.096 V shunt reference for industrial and automotive analog chains
The Texas Instruments LM4030BMF-4.096/NOPB is a precision shunt voltage reference delivering a fixed 4.096 V output with ±0.1% initial tolerance and a 20 ppm/°C temperature coefficient. As a shunt reference, it behaves like a Zener diode — it regulates by shunting current through an external resistor from the supply rail, making it suitable for positive or negative rail referencing without a dedicated supply pin. The 130 µA minimum cathode current allows low-power biasing, while the 30 mA output current can drive multiple ADC reference inputs or pull-up networks. Rated for -40°C to 125°C, it fits industrial process control, automotive sensor interfaces, and precision data-acquisition systems where a stable voltage rail is needed over a wide temperature span.
Lifecycle and sourcing
Texas Instruments lists the LM4030BMF-4.096/NOPB as Active. No end-of-life notification or last-time-buy schedule is in effect, so the part can be specified into new designs without near-term obsolescence risk. ROHS3 compliance covers current environmental regulations.
