Features (VS = ±5V, TJ = 25°C, Typical values unless specified). Voltage feedback architecture Unity gain bandwidth 250 MHz Supply voltage range ±2.5V to ±6V Slew rate 200 V/µsec Supply current 4.5 mA/channel Input common mode voltage −5.15V to +3.7V Output voltage swing (RL = 100Ω) −3.6V to 3.4V Input voltage noise 4.5 nV/ √Hz Input current noise 1.7 pA/ √Hz Settling Time to 0.01% 25 ns Description The LMH6654/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 ±2.5V to ±6V 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. The LMH6654/LMH6655 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/LMH6655 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 5-Pin SOT-23 and 8-Pin SOIC. The LMH6655 is packaged in 8-Pin MSOP and 8-Pin SOIC. The LMH6654/LMH6655 are built on National’s Advance VIP10 (Vertically Integrated PNP) complementary bipolar process. Applications ADC drivers Consumer video Active filters Pulse delay circuits xDSL receiver Pre-amps

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
