LM2901VDR2G

LM2901VDR2G Description

The LM2901VDR2G from onsemi is a quad, general-purpose voltage comparator designed for a wide range of analog signal processing applications. Housed in a compact 14-SOIC package and delivered in Tape & Reel (TR), this device is optimized for surface-mount assembly. It operates over a broad supply voltage range of 3V to 36V (single supply) or ±1.5V to ±18V (dual supply), making it versatile for both industrial and consumer electronics. With a low input offset voltage (max 7mV @ 5V) and minimal input bias current (0.25µA @ 5V), it ensures high precision in comparison tasks. The LM2901VDR2G is RoHS3 compliant and REACH unaffected, meeting stringent environmental standards.
