Features • 900 MHz −3 dB small signal bandwidth @ AV = 1 • 670 MHz −3 dB large signal bandwidth @ AV = 1 • −79 dB THD @ 20 MHz • −92 dB IMD3 @ fc = 20 MHz • 10 ns settling time to 0.1% • 600 ps clamp overdrive recovery time • 40 mV clamp accuracy with 100% Overdrive • −0.1 mV/°C clamp temperature drift • 4.5 to 12 supply voltage operation Description 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 PSOP and 8-pin LLP packages, and is part of our LMH high speed amplifier family. Applications • Differential ADC driver • Video over twisted pair • Differential line driver • Single end to differential converter • High speed differential signaling • IF/RF amplifier • SAW filter buffer/driver • CCD Output Limiting Amplifier • Automotive Safety Applications

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
