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 f eedback monolithics b y off ering 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, f ast sle wing, 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

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

) and 2.5pA/√Hz(i

)

noise sets a very low noise floor.
