PRODUCT BRIEF
Differential Line Driver
Features
The EL1504/5 contains two wideband
high-voltage drivers. It is designed to
• Complete ADSL differential driver
• 45V differential output drive into 200Ω
P-P
drive 45V
signals at 2MHz into a
P-P
• -60dBc typical output distortion at full output at 2MHz
200Ω load differentially with very low distortion.
• Drives 8 single-ended video loads, or 4 S-VHS loads, or 4
differential video loads
Both amplifiers are of the current-feedback type, giving high
slew rates while consuming moderate power. They retain
frequency response over a wide range of externally set
gains.
• Power surface-mount package
Applications
The EL1504/5 operate on ±5V to ±15V supplies, and
maintain their bandwidths and linearities over the supply
range.
• ADSL line interface
• HDSL line driver
The EL1504, in a 20-Pin Fused Lead SOIC package, has
eight center pins which are used as ground connections and
heat spreaders. This facilitates the use of external
• Video distribution amplifier
• Video twisted-pair line driver
heatsinking to increase the power handling of the device.
Ordering Information
The EL1505, in a 16-Pin SOIC package, is designed for
applications which do not require full power and where a
smaller PCB footprint is desirable. The packages are
specified for operation over the full -40°C to +85°C
temperature range.
