Description of Operation and
Application Information
Product Description
The EL5178 and EL5378 are wide bandwidth, low power and
single/differential ended to differential output amplifiers. The
EL5178 is a single channel differential amplifier. Since the IN- pin
and REF pin are tied together internally, the EL5178 can be used
as a single ended to differential converter. The EL5378 is a triple
channel differential amplifier. The EL5378 has a separate IN- pin
and REF pin for each channel. It can be used as
single/differential ended to differential converter. The EL5178
and EL5378 are internally compensated for closed loop gain of 1
or greater. Connected in gain of 2 and driving a 1k
Ω differential
load, the EL5178 and EL5378 have a -3dB bandwidth of
700MHz. Driving a 200
Ω differential load at gain of 2, the
bandwidth is about 320MHz. The EL5378 is available with a
power down feature to reduce the power while the amplifier is
disabled.
Input, Output, and Supply Voltage Range
The EL5178 and EL5378 have been designed to operate with a
single supply voltage of 5V to 10V or split supplies with its total
voltage from 5V to 10V. The amplifiers have an input common
mode voltage range from -4.3V 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 3.7V. If the input common mode or differential
mode signal is outside the above-specified ranges, it will cause
the output signal to become distorted.
The output of the EL5178 and EL5378 can swing from -3.8V to
+3.8V at 1k
Ω differential load at ±5V supply. As the load
resistance becomes lower, the output swing is reduced.
Differential and Common Mode Gain Settings
For EL5178, since the IN- pin and REF pin are bounded together as
the REF pin in an 8 Ld package, the signal at the REF pin is part of
the common mode signal and also part of the differential mode
signal. For the true balance differential outputs, the REF pin must be
tied to the same bias level as the IN+ pin. For a ±5V supply, just tie
the REF pin to GND if the IN+ pin is biased at 0V with a 50Ω or 75Ω
termination resistor. For a single supply application, if the IN+ is
biased to half of the rail, the REF pin should be biased to half of the
rail also.
The gain setting for EL5178 is expressed in Equation 1:
Where:
VREF = 0V
RF1 = RF2 = RF
EL5378 has a separate IN- pin and REF pin. It can be used as a
single/differential ended to differential converter. The voltage
applied at REF pin can set the output common mode voltage and
the gain is one.
The gain setting for EL5378 is expressed in Equation 2:
Where:
RF1 = RF2 = RF
