LM4040CIM3-2.0/NOPB – TEXAS INSTRUMENTS

The Texas Instruments LM4040CIM3-2.0/NOPB is a 2.0V precision shunt voltage reference in a compact SOT-23 (SC-70-6) surface-mount package. It’s characterized by its low temperature coefficient of ±20ppm/°C (typical) over a -40°C to +125°C operating temperature range, ensuring stable voltage output even under fluctuating conditions. The device operates with a reverse breakdown voltage of 7V minimum, and a typical output current of 100µA. Its low output noise of 50µVrms (typical) makes it suitable for applications demanding high precision. The “/NOPB” suffix denotes lead-free packaging compliant with RoHS directives._x000D_

The LM4040CIM3-2.0/NOPB excels in applications requiring a highly stable and accurate voltage reference, such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and precision comparators. Its small size and surface-mount capability are advantageous for space-constrained designs. The shunt architecture simplifies circuit design, eliminating the need for external current-limiting components commonly associated with zener diodes. Its superior temperature stability compared to many other voltage reference options minimizes drift and enhances overall system accuracy. The 2.0V output voltage is specifically chosen for many common microcontroller and data acquisition applications.
