LMH6654, LMH6655

SNOS956E –JUNE 2001–REVISED AUGUST 2014

LMH6654, LMH6655 Single and Dual Low Power, 250 MHz, Low Noise Amplifiers

1 Features

3 Description

The LMH6654 and LMH6655 single and dual high

speed voltage feedback amplifiers are designed to

have unity-gain stable operation with a bandwidth of

250 MHz. They operate from ±2.5 V to ±6 V and each

channel consumes only 4.5 mA. The amplifiers

feature very low voltage noise and wide output swing

to maximize signal-to-noise ratio, and possess a true

single supply capability with input common mode

voltage range extending 150 mV below negative rail

and within 1.3 V of the positive rail. The high speed

and low power combination of the LMH6654 and

LMH6655 make these products an ideal choice for

many portable, high speed applications where power

is at a premium.
