STM32L471QEI7 STMicroelectronics 32bit MCU

STM32L471QEI7 Overview

The LMV331, LMV393 and LMV339 are the single/dual/quad and low voltage versions of the industry standard LM339 and LM393. They can operate with a supply voltage ranging from 2.7 to 5 V, and exhibit a lower current consumption than their predecessors LM339 and LM393. These devices are a perfect choice for low-voltage applications.

The LMV3xx are available in tiny packages, making them ideal for applications where space saving is a constraint.
The devices are designed to operate in the temperature range of -40°C to +85°C and are suitable for a variety of applications.
