Single Supply Differential Line Driver
Due to its outstanding overall performance on low supply volt-
ages, the AD813 makes possible exceptional differential trans-
mission on very low power. The circuit of Figure 59 will convert
a single-ended, ground referenced signal to a differential signal
whose common-mode reference is set to one half the supply
voltage. This allows for a greater than 2 V peak-to-peak signal
swing on a single 3 V power supply. A bandwidth over 30 MHz
is achieved with 20 mA of output drive on only 30 mW of quies-
cent power (excluding load current).

3:1 Video Multiplexer
Wiring the amplifier outputs together will form a 3:1 mux with
outstanding gain flatness. Figure 55 shows a recommended
configuration which results in –0.1 dB bandwidth of 20 MHz
and OFF channel isolation of 60 dB at 10 MHz on
±5 V sup-
plies. The time to switch between channels is about 180 ns.
Switching time is only slightly affected by signal level.
