The LMH6657/6658 are low cost op amps operating from a single supply with an extended input voltage range of up to V- 。 Based on an easy-to-use voltage feedback topology with 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, and more.
The - 3dB BW used is100MHz(AV = 2) and DG and DP of 0.03% and 0.10°, respectively, the LMH6657/6658 is ideal for video applications. The output stage can typically provide a swing of around 1V of 80 mA, regardless of whether it is 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-Mitigation amplifies low-level signals, and system ground can reach or approach. With low distortion and fast settling, the LMH6657/6658 can provide buffered A/D and D/A applications.
The versatility and ease of use of the LMH6657/6658 is further extended and even offers the high slew rates of these tiny packages, such as the high-speed operational amplifier in the SOT23-5 package, and the SC70 with SOIC-8 and MSOP-8.
