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.
With external gain set resistors and integrated common mode feedback, the LMH6553 can be configured as either a differential input to differential output or single ended input to differential output gain block. The LMH6553 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 LMH6553 is available in 8-pin SO PowerPAD and 8-pin WSON packages, and is part of our LMH high speed amplifier family.
