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 tired together internally, the EL5171
can be used as a single ended to differential converter. The
EL5371 is a triple channel differential amplifier. The EL5371
have a separate IN- pin and REF pin for each channel. It can
be used as single/differential ended to differential converter.
The EL5171 and EL5371 are internally compensated for
closed loop gain of +1 of 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 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 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 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 tired to the same bias level as
the IN+ pin. For a ±5V supply, just tire 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 EL5171 is:
Where:
VREF = 0V
RF1 = RF2 = RF
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.
