Data Sheet
FEATURES
Triple high speed fully differential driver 700 MHz, −3 dB, 2 V p-p bandwidth (AD8146/AD8148) 600 MHz, −3 dB, 2 V p-p bandwidth (AD8147) 200 MHz, 0.1 dB, 2 V p-p bandwidth 3000 V/μs slew rate
Fixed gain (AD8146/AD8147: G = 2, AD8148: G = 4) Differential or single-ended input to differential output
Can be used as differential-to-differential receiver Drives one or two 100 Ω UTP cables Adjustable output common-mode voltage (AD8146) Internal common-mode feedback network
Output balance error −50 dB @ 50 MHz On-chip, sync-on common-mode encoding (AD8147/AD8148) Output pull-down feature for line isolation Low power: 57 mA @ 5 V for 3 drivers (AD8146) Wide supply voltage range: +5 V to ±5 V Available in a small 4 mm × 4 mm LFCSP
