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. The output stage can typically supply 80mA into the load with a swing of about 1V from either rail.

For Industrial applications, the LMH6657/6658 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, LMH6657/6658 can provide buffering for A/D and D/A applications.

The LMH6657/6658 versatility and ease of use is extended even further by offering these high slew rate , high speed Op Amps in miniature packages such as SOT23-5, SC70, SOIC-8, and MSOP-8. Refer to the Ordering Information section for packaging options available for each device.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
