LMH6657/LMH6658 270MHz Single Supply, Single & Dual Amplifiers October 2004 LMH6657/LMH6658 270MHz Single Supply, Single & Dual Amplifiers General Description The LMH6657/6658 are low-cost operational amplifiers that operate from a single supply with input voltage range extending below the V−. Based on easy to use voltage feedback topology and boasting fast slew rate (700V/µs) and high speed (140MHz GBWP), the LMH6657 (Single) and LMH6658 (dual) can be used in high speed large signal applications. These applications include instrumentation, communication devices, set-top boxes, etc. With a -3dB BW of 100MHz (AV = +2) and DG & DP of 0.03% & 0.10˚ respectively, the LMH6657/6658 are well suited for video applications.
