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’shigh performance includes
an extremely fast 800MHz small signal bandwidth (0.5
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 100Ω load.

Featuring a patented closed loop design, the CLC111 offers
nearly ideal unity gain (0.996) with a very low (1.4Ω) 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’sexcellentperformance 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.
