Comlinear CLC440
High-Speed, Low-Power, Voltage Feedback Op Amp
General Description
Features
■
Unity-gain stable
The Comlinear CLC440 is a wideband, low-power, voltage feedback
op amp that offers 750MHz unity-gain bandwidth, 1500V/µs slew
rate, and 90mA output current. For video applications, the CLC440
sets new standards for voltage feedback monolithics by offering
the impressive combination of 0.015% differential gain and
0.025° differential phase errors while dissipating a mere 70mW.

The CLC440 incorporates the proven properties of Comlinear’s
current feedback amplifiers (high bandwidth, fast slewing, etc.) into a
“classical” voltage feedback architecture. This amplifier possesses
truly differential and fully symmetrical inputs both having a high
900kΩ impedance with matched low input bias currents.
Furthermore, since the CLC440 incorporates voltage feedback, a
specific R is not required for stability. This flexibility in choosing R

Unlike several other high-speed voltage feedback op amps, the
CLC440 operates with a wide range of dual or single supplies
allowing for use in a multitude of applications with limited supply
availability. The CLC440’s low 3.5nV/√Hz(e ) and 2.5pA/√Hz(i )
