Overview
The LMV393IDGKR is a dual general-purpose low-voltage comparator manufactured by Texas Instruments. It is part of the LMV331, LMV393, and LMV339 family, which are low-voltage versions of the industry-standard LM393 and LM339 comparators. These devices are designed to operate over a supply voltage range of 2.7 V to 5.5 V, making them suitable for a wide range of low-voltage applications.
The LMV393IDGKR is particularly noted for its low power consumption, low output saturation voltage, and open-drain output, which provides maximum flexibility in circuit design. It is packaged in a VSSOP (DGK) package with 8 pins and operates over a temperature range of -40°C to 125°C.
