Life Support Policy
National’s products are not authorized for use as critical components in life support devices or systems without the express written approval of
the president of National Semiconductor Corporation. As used herein:
1. Life support devices or systems are devices or systems which, a) are intended for surgical implant into the body, or b) support or
sustain life, and whose failure to perform, when properly used in accordance with instructions for use provided in the labeling, can
be reasonably expected to result in a significant injury to the user.
2. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to
cause the failure of the life support device or system, or to affect its safety or effectiveness.

Current Feedback Amplifiers
Some of the key features of current feedback
technology are:
I
Independence of AC bandwidth and voltage gain
I
Inherently stable at unity gain
I
Adjustable frequency response with R
f
I
High slew rate
I
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:
A
v
is the closed loop DC voltage gain
R
f
is the feedback resistor
Z(j
ω
) is the open loop transimpedance gain
The denominator of Equation 1 is approximately
equal to 1 at low frequencies. Near the -3dB corner
frequency, the interaction between R
f
and Z(j
ω
)
dominates the circuit performance. The value of the
feedback resistor has a large affect on the circuits
performance. Increasing R
f
has the following affects:
I
Decreases loop gain
I
Decreases bandwidth
I
Reduces gain peaking
I
Lowers pulse response overshoot
I
Affects frequency response phase linearity
Layout Considerations
A proper printed circuit layout is essential for achieving
high frequency performance. National provides
evaluation boards for the CLC5644 (CLC730024 - DIP,
CLC730031 - SOIC) and suggests their use as a guide
for high frequency layout and as an aid for device
testing and characterization.
supply bypassing play major roles in high frequency
performance. Follow the steps below as a basis for
high frequency layout:
General layout and
I
Include 6.8
μ
F tantalum and 0.1
μ
F ceramic
capacitors on both supplies.
I
Place the 6.8
μ
F capacitors within 0.75 inches of
the power pins.
I
Place the 0.1
μ
F capacitors less than 0.1 inches
from the power pins.
I
Remove the ground plane under and around the
part, especially near the input and output pins to
reduce parasitic capacitance.
I
Minimize all trace lengths to reduce series
inductances.
I
Use flush-mount printed circuit board pins for
prototyping, never use high profile DIP sockets.
