Differential Line Driver/Receiver
General Description
• Complete ADSL differential driver
and receiver
• 45VP-P differential output drive
into 200Ω
• -60dB typical output distortion at
full output at 2MHz
• -73dB typical receive distortion at
15VP-P levels at 2MHz
• Drives 8 single-ended video loads,
or 4 S-VHS loads, or 4 differential
video loads
• Power surface-mount package
The EL1501C contains two wideband high-voltage drivers and two
receive amplifiers. It is designed to drive 45VP-P signals at 2MHz into
a 200Ω load differentially with very low distortion. The receive amplifiers also provide very low distortion and noise, and with external
resistors can be wired as a hybrid coupler.

All amplifiers are of the current-feedback type, giving high slewrates
while consuming moderate power. They retain frequency response
over a wide range of externally set gains.
The EL1501C operates on ±5V to ±15V supplies, and retains its bandwidths and linearities over the supply range.
Eight center package pins are used as ground connections and heat
spreaders, allowing a dissipation of 2W at the maximum ambient temperature of 85°C.
