Features: The TLV3501 fast speed comparator module deliver fast response with only 4.5ns transmission delay. This comparator module supports 2.7V to 5.5V power supply Featuring potentiometer, this module offer threshold adjustment from 0 to 0.9 times the supply. Choose between inverting or not inverting comparison modes via jumper or solder pad selection. The 35mm×33mm size allows easy integration into various electronic projects. Designed with reverse polarity protective, this module prevents damage from incorrect power connection. The high input impedance minimizes preceding circuits. Specifications: Component:Plastic Size:Approx.35x33mm/1.37x1.29inch Power supply +2.7V ~ +5.5V (5V power supply recommended, pay attention to polarity) Bandwidth: 200MHz Transmission delay: 4.5ns Package Includes: 1Pc Comparator Module note: 1.Please allow 1-2cm errors due to manual measurement, making sure that you not mind before order. 2.Due to the differences between different monitors, the picture may not reflect the actual of the item.
