CLC440
High-Speed, Low-Power, Voltage Feedback Op Amp
General Description
The 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 impres-
sive combination of 0.015% differential gain and 0.025° differen-
tial 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_f is not required for stability. This flexibility in choosing R_f
allows for numerous applications in wideband filtering and integration.
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_n) and 2.5pA/√Hz(i_n)
noise sets a very low noise floor.
