VIDEO_LOOP_THRU_AMPLIFIER
This video bandwidth amplifier rejects commonmode noise, such as 60- and 120-Hz hum. Bandwidth is typically 60 MHz for a differential gain of 2.The common-mode rejection is typically 45 dB.The design equations are: ADIFF ≥ 1R2 = R4 (select both for optimum bandwidth)R1=R2 (ADlFF-1)R3=R4 (ADIEF-1)
