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/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

Ω load.

Featuring a patented closed loop design, the CLC111 offers

nearly ideal unity gain (0.996) with a very low (1.4

Ω) 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.
