The LMH6657/6658 are low cost, single-supply op amps powered from V with input voltages 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), the LMH6657 (single) and LMH6658 (dual) can be used in high-speed large signal applications. These applications include instrumentation, communication equipment, set-top boxes, etc.
With the -3dB bandwidth is 100MHz (AV= 2) and DG and DP of 0.03% and 0.10°, respectively, LMH6657/6658 are ideal for video applications. The output stage can typically deliver 80 mA with about 1V swing regardless of 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-level signals can be amplified up to or near systematically. With low distortion and fast settling, the LMH6657/6658 can provide A/D and D/A application buffering.
The versatility and ease of use of the LMH6657/6658 offers a further expansion of high slew rate, high speed operational amplifiers such as SOT23-5, SC70, SOIC-8 and MSOP-8 in these tiny packages. Please refer to the Packaging Selection section for providing ordering information for each device.
