LM339ADR in LM339 / LM393 Comparators Family
The LM339ADR represents a high-precision sub-family of the industry-standard LM339 quad differential comparator series produced by Texas Instruments and other leading manufacturers. These devices consist of four independent voltage comparators designed to operate from a single power supply over a wide range of voltages. Featuring a lower offset voltage compared to the standard LM339, the ADR variant is optimized for applications requiring tighter voltage thresholds and reliable open-collector output switching in multi-channel configurations.
Variants in This Sub-Family
Variants within the LM339 sub-family primarily differ based on input offset voltage specifications and operating temperature ranges. The 'A' suffix in LM339ADR denotes a precision version with a tighter maximum offset voltage (2mV) compared to the standard LM339 (5mV). Packaging variants like the 'DR' suffix indicate small-outline integrated circuit (SOIC) tape-and-reel delivery, while other versions may offer TSSOP or PDIP form factors for space-constrained or prototyping needs.
