4.096 V series reference — precision for the analog rail
The Texas Instruments LM4140CCM-4.1/NOPB is a fixed 4.096 V series voltage reference in an 8-SOIC surface-mount package. Its ±0.1% initial tolerance and 10 ppm/°C temperature coefficient make it a fit for precision ADC/DAC reference rails, data-acquisition front-ends, and instrumentation where a stable, low-drift voltage is required. A 2.2 µVp-p noise floor from 0.1 Hz to 10 Hz keeps the reference clean for high-resolution measurements — weigh scales, load cells, and multimeter-grade inputs benefit directly.
Input range, output current, and supply budget
The device operates from a 1.8 V to 5.5 V input rail and delivers up to 8 mA to the load. Supply current is 400 µA typical.
Temperature grade and deployment envelope
Rated for 0°C to 70°C ambient, this is a commercial-temperature part.
Lifecycle and sourcing posture
Listed as Active and ROHS3 compliant. No second-source alternate is listed on the TI cross-reference, but the LM4132AMF-4.1/NOPB is a functional peer with tighter tolerance and wider temperature range if the design requires those margins.
