CLC5623 Operation
The CLC5623 is a current feedback amplifier fabricated in an
advanced complementary bipolar process. The CLC5623
operates from a single 5V supply or dual
Operating from a single supply, the CLC5623 has the
following features:
The CLC5623 performance is further enhanced in
supply applications as indicated in the
Characteristics table and
Current Feedback Amplifiers
Some of the key features of current feedback technology
are:
= +5V
• Provides 100mA of output current while consuming
• Offers low −85/-96dB 2nd & 3rd harmonic distortion
• Provides BW100MHz and 1MHz distortion
• Independence of AC bandwidth and voltage gain
• Inherently stable at unity gain
• Adjustable frequency response with feedback resistor

Current feedback operation can be described using a simple
equation. The voltage gain of a non-inverting or inverting
current feedback amplifier is approximated by Equation 1.
