The 8-DIP package (0.300\" width) is a through-hole footprint that suits prototype boards, legacy designs, and high-vibration assemblies where a socketed part is preferred over surface-mount. ## Supply range and input offset — the numbers that matter The supply range spans 2 V to 36 V on a single rail, or ±1 V to ±18 V with dual supplies — wide enough to work from a 3.3 V logic rail up to a 24 V industrial bus without a secondary regulator. Maximum quiescent current is 2.5 mA, so the comparator itself draws little power even at high rail voltages.","metaTitle":"LM2903N Dual General-Purpose Comparator, -40°C to 125°C","metaDescription":"LM2903N dual open-collector comparator in 8-DIP.
