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

µs. Even with this

minimal dissipation, the CLC109 can easily drive a demanding

100

Ω load. The buffer specifications are for a 100Ω load.

With its patented closed-loop topology, the CLC109 has significant

performance advantages over conventional open-loop designs.

Applications requiring low (2.8

Ω) 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.
