Fully differential RF ADC Driver
Overview
The TI-RF-DRV is a fully differential RF driver designed for differential signal processing applications. The driver can be used as a single-ended-to-differential amplifier or a differential-to-differential amplifier. Gain is adjusted externally by connected resistors. The device uses an internal feedback structure providing balanced output gain and phase matching. The common-mode level of differential outputs is adjusted by «VCM» voltage that allows to shift easily the input signals for driving single-supply ADCs. ESD-protection provided.
