SPECIFICATIONS

Description:

This module can realize single-ended to differential, single-ended input and double-ended output. The LMH6550 is a high performance voltage feedback differential amplifier. It has the advantages of high performance, low noise, and wide power supply voltage range. Provides excellent common-mode noise rejection and improved total harmonic distortion relative to op amps. The differential output of the LMH6550 help to balance the input of the differential ADC to achieve better ADC performance. Applying a voltage to the VOCM pin adjusts the common-mode level of the differential output, so that the input signal of driving single-supply ADC is easily level conversion. The LMH6550 is suitable for use as an IF amplifier in high-performance communication equipment.
