LMH6657/LMH6658

270MHz Single Supply, Single & Dual Amplifiers

General Description

The LMH6657/6658 are low-cost operational amplifiers that

operate from a single supply with input voltage range ex-

tending below the V

back 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 (A

& 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

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.
