Simplified Schematic
Description of Operation and
Application Information
Product Description
The EL5174 and EL5374 are wide bandwidth, low power and
single/differential ended to differential output amplifiers. The
EL5174 is a single channel differential amplifier. Since the IN-
pin and REF pin are tied together internally, the EL5174 can be
used as a single-ended to differential converter. The EL5374 is
a triple channel differential amplifier. The EL5374 has a
separate IN- pin and REF pin for each channel. It can be used
as single/differential ended to differential converter. The
EL5174 and EL5374 are internally compensated for closed
loop gain of +1 of greater. Connected in a gain of 1 and driving
a 1k
Ω differential load, the EL5174 and EL5374 have a -3dB
bandwidth of 550MHz. Driving a 200
Ω differential load at gain
of 2, the bandwidth is about 130MHz. The EL5374 is available
with a power-down feature to reduce the power while the
amplifier is disabled.
Input, Output and Supply Voltage Range
The EL5174 and EL5374 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 EL5174 and EL5374 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 EL5174, since the IN- pin and REF pin are bound 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 50
Ω 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 EL5174 is expressed in Equation 1:
Where:
VREF = 0V
RF1 = RF2 = RF
The EL5374 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 EL5374 is expressed in Equation 2:
Where:
RF1 = RF2 = RF
