85MHz Current Feedback Amplifier
Features
• -3dB bandwidth = 85MHz, A = 1
V
The EL2130 is a wideband current
mode feedback amplifier optimized for
gains between -10 and +10 while
• -3dB bandwidth = 75MHz, A = 2
V
• NTSC/PAL dG ≤ 0.03%, dP ≤ 0.1°
• 50mA output current
operating on ±5V power supplies. Built using Elantec's
Complementary Bipolar process, this device exhibits -3dB
bandwidths in excess of 85MHz at unity gain and 75MHz at
a gain of two. The EL2130 is capable of output currents in
excess of 50mA giving it the ability to drive either double or
single terminated 50Ω coaxial cables.
• Drives ±2.5V into 100Ω load
• Low voltage noise = 4nV√Hz
• Current mode feedback
• Low cost
Exhibiting a Differential Gain of 0.03% and a Differential
Phase of 0.1° at NTSC and PAL frequencies, the EL2130 is
an excellent low cost solution to most video applications.
Applications
In addition, the EL2130 exhibits very low gain peaking,
typically below 0.1dB to frequencies in excess of 40MHz as
well as 50ns settling time to 0.2% making it an excellent
choice for driving flash A/D converters.
• Video amplifier
• Video distribution amplifier
• Residue amplifiers in ADC
• Current to voltage converter
• Coaxial cable driver
The device is available in the plastic 8-pin narrow-body small
outline (SO) and the 8-pin mini DIP packages, and operates
over the temperature range of 0°C to +75°C

Applications Information
Power Supply Bypassing
The EL2130 will exhibit ringing or oscillation if the power
supply leads are not adequately bypassed. 0.1µF ceramic
disc capacitors are suggested for both supply pins at a
distance no greater than 1/2 inch from the device. Surface
mounting chip capacitors are strongly recommended.
Lead Dress
A ground plane to which decoupling capacitors and gain
setting resistors are terminated will eliminate overshoot and
ringing. However, the ground plane should not extend to the
vicinity of both the non-inverting and inverting inputs (pins 3
and 2) which would add capacitance to these nodes, and
lead lengths from these pins should be made as short as
possible.
Use of sockets, particularly for the SO package, should be
avoided if possible. Sockets add parasitic inductance and
capacitance which will result in peaking and overshoot.
Video Characteristics and Applications
AC Test Circuit
Frequency domain testing is performed at Elantec using a
computer controlled HP model 8656B Signal Generator and
an HP Model 4195A Network/Spectrum Analyzer. The DUT
test board is built using microwave/strip line techniques, and
solid coaxial cables route the stimulus to the DUT socket.
Signals are routed to and from the DUT test fixture using
subminiature coaxial cable.
Differential Gain and Phase are tested at a noise gain of 2
with 100Ω load. Gain and Phase measurements are made
with a DC input reference voltage at 0V and compared to
those made at V
to 30MHz.
equal to 0.7V at frequencies extending
REF
The EL2130 is capable of driving 100Ω to a minimum of 2.5V
peak which means that it can naturally drive double
terminated (50Ω) coaxial cables.
Capacitive Loads
As can be seen from the Bode plot, the EL2130 will peak into
capacitive loads greater than 20pF. In many applications
such as flash A/Ds, capacitive loading is unavoidable. In
these cases, the use of a snubber network consisting of a
100Ω resistor in series with 47pF capacitor from the output
to ground is recommended.
