CLC446
400MHz, 50mW Current-Feedback Op Amp
November 1998
General Description
The National CLC446 is a very high-speed unity-gain-stable cur-
rent-feedback op amp that is designed to deliver the highest lev-
els of performance from a mere 50mW quiescent power. It pro-
vides a very wide 400MHz bandwidth, a 2000V/µs slew rate and
900ps rise/fall times. The CLC446 achieves its superior speed-
vs-power using an advanced complementary bipolar IC process
and National’s current-feedback architecture.
The CLC446 is designed to drive video loads with very low
differential gain and phase errors (0.02%, 0.03°). Combined with
its very low power (50mW), the CLC446 makes an excellent
choice for NTSC/PAL video switchers and routers. With its very
quick edge rates (900ps) and high slew rate (2000V/µs), the
CLC446 also makes an excellent choice for high-speed, high-
resolution component RGB video systems.
The CLC446 makes an excellent low-power high-resolution A/D
converter driver with its very fast 9ns settling time (to 0.1%) and
low harmonic distortion.
The combination of high performance and low power make
the CLC446 useful in many high-speed general purpose
applications. Its current-feedback architecture maintains consistent
performance over a wide gain range and signal levels. DC gain
and bandwidth can be set independently. Also, either maximally
flat AC response or linear phase response can be emphasized.
