Description of Operation and
Application Information
Product Description
The EL5171 and EL5371 are wide bandwidth, low power and
single-ended to differential output amplifiers. The EL5171 is a
single channel differential amplifier. Since the IN- pin and REF
pin are tied together internally, the EL5171 can be used as a
single-ended to differential converter. The EL5371 is a triple
channel differential amplifier. The EL5371 has a separate IN-
pin and REF pin for each channel. It can be used as a
single/differential ended to differential converter. The EL5171
and EL5371 are internally compensated for closed loop gain of
+1 or greater. Connected in gain of 1 and driving a 1k
Ω
differential load, the EL5171 and EL5371 have a -3dB
bandwidth of 250MHz. Driving a 200
Ω differential load at gain
of 2, the bandwidth is about 30MHz. The EL5371 is available
with a power-down feature to reduce the power while the
amplifier is disabled.
Input, Output, and Supply Voltage Range
The EL5171 and EL5371 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 -4.5V 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 to become distorted.
The output of the EL5171 and EL5371 can swing from -3.9V to
+3.9V 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 EL5171, 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 50Ω or
75
Ω 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 EL5171 is expressed in Equation 1:
Where:
VREF = 0V
RF1 = RF2 = RF
The EL5371 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 EL5371 is expressed in Equation 2:
