LM339BIDR in LM339 / LM393 Comparators Family
The LM339BIDR is part of the industry-standard LM339 family of quad differential comparators manufactured by Texas Instruments and other leading semiconductor vendors. Designed for operation from a single power supply over a wide range of voltages, these devices feature a common-mode input voltage range that includes ground. The LM339BIDR specifically offers improved performance over the original LM339 series, featuring lower offset voltage and tighter specifications for modern industrial and automotive sensing circuits.
Variants in This Sub-Family
Variants within the LM339 family primarily differ by their operating temperature ranges and input offset voltage specifications. The 'B' suffix in LM339BIDR denotes an improved version with a lower maximum input offset voltage (2mV vs 5mV) compared to the standard LM339. Other variants like the LM2901 are chemically identical but qualified for wider temperature ranges (up to 125C) for automotive or harsh industrial environments.
