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 (0.5Vpp) 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 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's excellent
performance on reduced or single supply voltages.
Constructed using an advanced, complementary bipolar process and
Comlinear's proven high-performance architectures, the CLC111 is
available in several versions to meet a variety of requirements.
