3 Description
The LMH6552 device is a high-performance, fully
differential amplifier designed to provide the
exceptional signal fidelity and wide large-signal
bandwidth necessary for driving 8-bit to 14-bit high-
speed data acquisition systems. Using TI's
proprietary differential current mode input stage
architecture, the LMH6552 allows operation at gains
greater than unity without sacrificing response
flatness, bandwidth, harmonic distortion, or output
noise performance.
With external gain set resistors and integrated
common mode feedback, the LMH6552 can be
configured as either a differential input to differential
output or single-ended input to differential output gain
block. The LMH6552 can be AC- or DC-coupled at
the input which makes it suitable for a wide range of
applications, including communication systems and
high-speed oscilloscope front ends. The performance
of the LMH6552 driving an ADC14DS105 device is
86 dBc SFDR and 74 dBc SNR up to 40 MHz.
The LMH6552 is available in an 8-pin SOIC package
as well as a space-saving, thermally enhanced 8-pin
WSON package for higher performance.
