It is designed to provide highly accurate and stable voltage reference for a wide range of applications. This device features a variety of features, including low power consumption, low voltage operation, low error, and a wide operating temperature range.

Application Field and Working Principle

The LM4050BEM3X-8.2/NOPB can be used for several different applications, such as voltage-to-frequency and frequency-to-voltage conversion, as well as voltage regulation in applications such as DC-DC converters and Sampling Amplifiers. It can be used in applications such as resistive sensing and current sensing, signal attenuation and signal isolation, data and clock synchronization, and circuit protection. The LM4050BEM3X-8.2/NOPB includes two precision opto-isolated inputs, one with a buffered reference voltage and the other with a wide range of programmable thermally-controlled voltage levels.The working principle of LM4050BEM3X-8.2/NOPB is based on the use of a variant of a Zener diode, known as a “regulator”. A regulator is a voltage source device which can be configured to maintain a fixed output voltage, regardless of input or load changes. The LM4050BEM3X-8.2/NOPB achieves this using a series of precisely aligned avalanche diodes to reduce the magnitude of any transient variations in current. The avalanche diodes work to absorb any excess current present in the output voltage, regulating the output to a given set point.
