LMH6655

LMH6654/55 Single/Dual Low Power, 250 MHz, Low Noise Amplifiers August 2001 LMH6654/55 Single/Dual Low Power, 250 MHz, Low Noise Amplifiers General Description The LMH6654/55 single and dual high speed, voltage feedback amplifiers are designed to have unity-gain stable operation with a bandwidth of 250MHz. They operate from ± 2.5V to ± 6V and each channel consumes only 4.5mA. The 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.
