LMH6654/55
Single/Dual Low Power, 250 MHz, Low Noise Amplifiers
General Description
The LMH6654/55 single and dual high speed, voltage feed-
back amplifiers are designed to have unity-gain stable op-
eration with a bandwidth of 250MHz. They operate from
±
amplifiers feature very low voltage noise and wide output
swing to maximize signal-to-noise ratio.
The LMH6654/55 have a true single supply capability with
input common mode voltage range extending 150 mV below
negative rail and within 1.3V of the positive rail.
LMH6654/55 high speed and low power combination make
these products an ideal choice for many portable, high
speed application where power is at a premium.
The LMH6654 is packaged in SOT23-5 and SOIC-8. The
LMH6655 is packaged in MSOP-8 and SOIC-8.
The LMH6654/55 are built on National’s Advance VIP10
(Vertically Integrated PNP) complementary bipolar process.
