CLC5633 Operation
The CLC5633 is a current feedback buffer fabricated in an
advanced complementary bipolar process. The CLC5633
operates from a single 5V supply or dual
Operating from a single 5V supply, the CLC5633 has the
following features:
The CLC5633 performance is further enhanced in
ply applications as indicated in the
teristics table and
If gains other than +1, −1, or +2V/V are required, then the
CLC5602 can be used. The CLC5602 is a current feedback
amplifier with near identical performance and allows for ex-
ternal feedback and gain setting resistors.

Current Feedback Amplifiers
Some of the key features of current feedback technology
are:
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.
where:
• Independence of AC bandwidth and voltage gain
• Inherently stable at unity gain
• Adjustable frequency response with feedback resistor
• High slew rate
• Fast settling
