LMH6553MR/NOPB, Differential Amplifiers 900Mhz Diff Amp W/ Clamp

The LMH6553MR/NOPB is a 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 600ps ensures the amplifier output rapidly recovers from a clamping event and quickly resumes to follows the input signal. The LMH6553 delivers exceptional bandwidth, distortion and noise performance ideal for driving ADCs up to 14-bit. 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.
