Description of Operation and Application
Information
Product Description
The EL5170 and EL5370 are wide bandwidth, low power
and single/differential ended to differential output amplifiers.
They have a fixed gain of 2. The EL5170 is a single channel
differential amplifier. The EL5370 is a triple channel
differential amplifier. The EL5170 and EL5370 have a -3dB
bandwidth of 100MHz while driving a 200Ω differential load.
The EL5170 and EL5370 are available with a power down
feature to reduce the power while the amplifiers are
disabled.
Input, Output and Supply Voltage Range
The EL5170 and EL5370 have been designed to operate
with a single supply voltage of 5V to 10V or a split supplies
with its total voltage from 5V to 10V. The amplifiers have an
input common mode voltage range from -4.5V to 3.4V for
±5V supply. The differential mode input range (DMIR)
between the two inputs is from -2.3V to +2.3V. The input
voltage range at the REF pin is from -3.3V to 3.8V. If the
input common mode or differential mode signal is outside the
above-specified ranges, it will cause the output signal
distorted.
The output of the EL5170 and EL5370 can swing from -3.3V
to 3.6V at 200Ω differential load at ±5V supply. As the load
resistance becomes lower, the output swing is reduced.
