General Description

The Comlinear CLC427 is a dual wideband voltage-feedback

operational amplifier that is uniquely designed to provide high

performance from a single power supply. This CLC427 provides

near rail-to-rail operation and the common-mode input range

includes the negative rail. Each of the CLC427’s amplifiers offers

plenty of headroom for single-supply applications as evidenced

Fabricated with a high-speed complementary bipolar process,

the CLC427 delivers a wide 94MHz unity-gain bandwidth, 7.5ns

rise/fall time and 150V/

µs slew rate. For single supply applications

such as video distribution or desktop multimedia, the CLC427

offers low 0.35%, 0.55° differential gain and phase errors.

Each of the CLC427’s amplifiers provides high signal fidelity

Combining this high fidelity performance with CLC427’s quick

46ns settling time to 0.1% makes it an excellent choice for ADC

buffering.

With its traditional voltage-feedback architecture and high-speed

performance, the CLC427 is the perfect choice for composite

signal conditioning circuit functions such as active filters,

integrators, differentiators, simple gain blocks and buffering.
