CLC109
Low-Power, Wideband, Closed-Loop Buffer
Single-Supply Circuit
Typical Application
General Description
The CLC109 is a high-performance, closed-loop monolithic buffer
intended for power sensitive applications. Requiring only 35mW of
quiescent power (±5V supplies), the CLC109 offers a high bandwidth
of 270MHz (0.5V
pp
) and a slew rate of 350V/
μ
s. Even with this
minimal dissipation, the CLC109 can easily drive a demanding
100
load. The buffer specifications are for a 100
load.
With its patented closed-loop topology, the CLC109 has significant
performance advantages over conventional open-loop designs.
Applications requiring low (2.8
)
output impedance and nearly
ideal unity gain (0.997) through very high frequencies will benefit
from the CLC109's superior performance. Power sensitive
applications will benefit from the CLC109's excellent performance
on reduced or single supply voltages.
Constructed using an advanced, complementary bipolar process
and Comlinear's proven high-performance architectures, the
CLC109 is available in several versions to meet a variety of
requirements.
