Simplified Schematic
Description of Operation and Application
Information
Product Description
The EL5176 is a wide bandwidth, low power and
single/differential ended to differential output amplifier. It can
be used as single/differential ended to differential converter.
The EL5176 is internally compensated for closed loop gain
of +1 of greater. Connected in gain of 1 and driving a 1k
differential load, the EL5176 has a -3dB bandwidth of
250MHz. Driving a 200
differential load at gain of 2, the
bandwidth is about 30MHz. The EL5176 is available with a
power down feature to reduce the power while the amplifier
is disabled.
Input, Output, and Supply Voltage Range
The EL5176 has 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 amplifier has 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 EL5176 can swing from -3.8V to +3.9V at
1k
differential load at ±5V supply. As the load resistance
becomes lower, the output swing is reduced.
Differential and Common Mode Gain Settings
The voltage applied at REF pin can set the output common
mode voltage and the gain is one. The differential gain is set
by the R
F
and R
G
network.
The gain setting for EL5176 is:

Choice of Feedback Resistor and Gain Bandwidth
Product
For applications that require a gain of +1, no feedback
resistor is required. Just short the OUT+ pin to FBP pin and
OUT- pin to FBN pin. For gains greater than +1, the
feedback resistor forms a pole with the parasitic capacitance
at the inverting input. As this pole becomes smaller, the
amplifier's phase margin is reduced. This causes ringing in
the time domain and peaking in the frequency domain.
Therefore, R
F
has some maximum value that should not be
exceeded for optimum performance. If a large value of R
F
must be used, a small capacitor in the few Pico farad range
