The LMH6657/6658 is a low-cost, single-supply operational amplifier with input voltage below the extended range- Based on an easy-to-use voltage feedback topology and fast slew rate (700V/μs) and high speed (GBWP at 140MHz), LMH6657 (single) and LMH6658 (dual) can be used for high-speed high-signal applications. These applications include instrumentation, communication equipment, set-top boxes, and more.
With a bandwidth of 100MHz (AV = 2) and a bandwidth of 3dB, it is ideal for video applications LMH6657/0.10° and 0.10° of DG and DP, respectively. The output stage typically delivers 80 mAh with about 1V swing, from rail to load.
For industrial applications, the LMH6657/6658 is an excellent cost-saving option. The input reference voltage is low in noise, and the input voltage can be extended below V-mitigating low levels to achieve or near systematic amplification. With low distortion and fast settling, the LMH6657/6658 can provide A/D and D/A application buffering.
The LMH6657/6658 offers versatility and ease of use, offering further expansion in these miniature packages with high-slewd, high-speed operational amplifiers such as SOT23-5, SC70, SOIC-8 and MSOP-8. Please refer to the Packaging Selection Provide Ordering Information for Each Device section.
