LMH6658 Datasheet 270MHz Single Supply Single/Dual Amplifiers

Manufacturer: National Semiconductor (now Texas Instruments)

General 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.
