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.

The LMH6654 and LMH6655 are built on TI’s Advance VIP10 (Vertically Integrated PNP) complementary bipolar process.

The LMH6654 is packaged in 5-Pin SOT-23 and 8-Pin SOIC. The LMH6655 is packaged in 8-Pin VSSOP (DGK) and 8-Pin SOIC.
