Check for Samples: LMH6553 FEATURES DESCRIPTION 1 23 The LMH6553 is a 900 MHz differential amplifier with
an integrated adjustable output limiting clamp. The
clamp increases system performance and provides
transient over-voltage protection to following stages.
The internal clamp feature of the LMH6553 reduces
or eliminates the need for external discrete overload
protection networks. When used to drive ADCs, the
amplifier's output clamp allows low voltage ADC
inputs to be protected from being overdriven and
damaged by large input signals appearing at the
system input. Fast overdrive recovery of 600 ps
ensures the amplifier output rapidly recovers from a
clamping event and quickly resumes to follow the
input signal. The LMH6553 delivers exceptional
bandwidth, distortion, and noise performance ideal for
driving ADCs up to 14-bits. The LMH6553 could also
be used for automotive, communication, medical, test
and measurement, video, and LIDAR applications. 900 MHz -3 dB Small Signal
