CLC111
Ultra High Slew Rate, Closed Loop Buffer
General Description
The CLC111 is a high performance, closed loop, monolithic
buffer
designed
for
applications
requiring
frequency signals. The CLC111’s high performance includes
an extremely fast 800MHz small signal bandwidth (0.5
pp)
and an ultra high (3500V/μs) slew rate while requiring only
10.5mA quiescent current. Signal fidelity is maintained with
low harmonic distortion (62dBc 2nd and 3rd harmonics at
20MHz). These performance characteristics are for a
demanding 100
load.
Featuring a patented closed loop design, the CLC111 offers
nearly ideal unity gain (0.996) with a very low (1.4
) output
impedance. The CLC111 is ideally suited for buffering video
signals with its 0.15%/0.04 differential gain and phase
performance at 4.43MHz. Power sensitive applications will
benefit from the CLC111’s excellent performance on reduced
or single supply voltages.
Constructed using an advanced, complementary bipolar
process
and
National’s
proven
high
architectures, the CLC111 is available in several versions to
meet a variety of requirements.
