The LMH6657 and LMH6658 devices 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 (700 V/µs) and high speed (140 MHz 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, and so forth.

With a –3dB BW of 100 MHz (AV = +2) and DG & DP of 0.03% & 0.10° respectively, the LMH6657 and LMH6658 are well suited for video applications. The output stage can typically supply 80 mA into the load with a swing of about 1 V from either rail.

For Industrial applications, the LMH6657 and LMH6658 are excellent cost-saving choices. Input referred voltage noise is low and the input voltage can extend below V− to ease amplification of low level signals that could be at or near the system ground. With low distortion and fast settling, LMH6657 and LMH6658 can provide buffering for A/D and D/A applications.

The LMH6657 and LMH6658 versatility and ease of use is extended even further by offering these high slew rate, high-speed operational amplifiers in miniature packages such as SOT-23-5, SC70, SOIC-8, and VSSOP-8.
