CLC452 Operation
The CLC452 is a current feedback amplifier built in an
advanced complementary bipolar process. The CLC452
operates from a single 5V supply or dual ±5V supplies.
Operating from a single supply, the CLC452 has the
following features:
s
Provides 100mA of output current while
consuming 15mW of power
s
Offers low -78/-85dB 2nd and 3rd harmonic
distortion
s
Provides BW > 80MHz and 1MHz distortion
< -70dBc at Vo = 2.0Vpp
The CLC452 performance is further enhanced in ±5V
supply applications as indicated in the
±5V Electrical
Characteristics table and ±5V Typical Performance plots.
Current Feedback Amplifiers
Some of the key features of current feedback technology
are:
s
Independence of AC bandwidth and voltage gain
s
Inherently stable at unity gain
s
Adjustable frequency response with feedback resistor
s
High slew rate
s
Fast settling
Current feedback operation can be described using a simple
equation. The voltage gain for a non-inverting or inverting
current feedback amplifier is approximated by Equation 1.
Equation 1
where:
s
Av is the closed loop DC voltage gain
s
Rf is the feedback resistor
s
Z(j
ω) is the CLC452’s open loop transimpedance
gain
s
is the loop gain
The denominator of Equation 1 is approximately equal to
1 at low frequencies. Near the -3dB corner frequency, the
interaction between Rf and Z(jω) dominates the circuit
performance. The value of the feedback resistor has a
large affect on the circuits performance. Increasing Rf
has the following affects:
s
Decreases loop gain
s
Decreases bandwidth
s
Reduces gain peaking
s
Lowers pulse response overshoot
s
Affects frequency response phase linearity
Refer to the
Feedback Resistor Selection section for
more details on selecting a feedback resistor value.

CLC452 Design Information
Single Supply Operation (VCC = +5V, VEE = GND)
The specifications given in the
+5V Electrical Character-
istics table for single supply operation are measured with
a common mode voltage (Vcm) of 2.5V. Vcm is the volt-
age around which the inputs are applied and the
output voltages are specified.
Operating from a single +5V supply, the Common Mode
Input Range (CMIR) of the CLC452 is typically +0.8V to
+4.2V. The typical output range with RL=100Ω is +1.0V
to +4.0V.
For single supply DC coupled operation, keep input
signal levels above 0.8V DC. For input signals that drop
below 0.8V DC, AC coupling and level shifting the signal
are recommended. The non-inverting and inverting
configurations for both input conditions are illustrated in
the following 2 sections.
DC Coupled Single Supply Operation
Figures 1 and 2 show the recommended non-inverting
and inverting configurations for input signals that remain
above 0.8V DC.
