LM4140BCM-1.2 Description

Short technical summary and product information.

The Texas Instruments LM4140BCM-1.2 is a high-accuracy, low-power voltage reference designed for demanding applications. This series reference provides a stable 1.2V output voltage with an initial accuracy of 0.1% and a low temperature coefficient of 3 ppm/°C (A Grade).

 

Key features include ultra-low noise (2.2 µVPP from 0.1 Hz to 10 Hz), a low dropout voltage of 20 mV at 1mA, and a typical supply current of 0.23 mA. The device operates from a 1.8V to 5.5V input range and includes an enable pin for power management. It is available in a compact SOIC package.

 

This voltage reference is suitable for applications requiring precise and stable voltage references, such as data acquisition systems, power management circuits, and portable instrumentation. Its low power consumption and small footprint make it ideal for space-constrained designs.
