CLC111
Ultra High Slew Rate, Closed Loop Buffer
General Description
The CLC111 is a high performance, closed loop, monolithic
buffer
designed
for
applications
requiring
very
high
frequency signals. The CLC111's high performance includes
an extremely fast 800MHz small signal bandwidth (0.5
pp)
and an ultra high (3500V/s) 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
performance
architectures, the CLC111 is available in several versions to
meet a variety of requirements.
Enhanced Solutions (Military/Aerospace)
SMD Number: contact factory
Space level versions also available.

Note 1: "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation.
Note 2: Min/max ratings are based on product characterization and simulation. Individual parameters are tested as noted. Outgoing quality levels are determined
from tested parameters.
Note 3: AJ-level: spec. is 100% tested at +25C.
