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.
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.
