illustrate

The LMH6553 is an integrated differential amplifier with adjustable output limit clamping of 900 MHz. Fixtures that improve system performance and transient overvoltage protection provide the following stages. The LMH6553's internal clamping function reduces or eliminates the need for an external discrete overload protection network. When used to drive ADC The output clamp of the amplifier allows the low voltage ADC input to appear in the system's input to protect large input signals from excessive and damaged protection. Fast overload recovery of 600 ps ensures that the output of the amplifier recovers quickly from clamping events and quickly recovers following the input signal. The LMH6553 is ideal for superior bandwidth, distortion and noisy drivability ADC Up to 14 bits. The LMH6553 can also be used in automotive, communications, medical, test and measurement, video, and lidar applications.

With external gain-setting resistors and integrated common-mode feedback, the LMH6553 can be configured as a differential input-to-differential output or single-ended input-to-differential output gain block. The LMH6553 can be AC or DC coupled to inputs, which makes it suitable for a wide range of applications, including communication systems and high-speed oscilloscope front ends. The LMH6553 is available in 8-pin PSOP and 8-pin LLP packages and is part of the LMH family of high-speed amplifiers.
