Comlinear CLC423
94MHz, Single Supply Voltage Feedback Op Amp
General Description
The Comlinear CLC423 is a wideband voltage-feedback
operational amplifier that is uniquely designed to provide high
performance from a single power supply. The CLC423 provides
near rail-to-rail operation and the common-mode input range
includes the negative rail. The CLC423 offers plenty of head-
room for single-supply applications as evidenced by its 4.3V
output voltage from a single 5V supply.
Fabricated with a high-speed complementary bipolar process, the
CLC423 delivers a wide 94MHz unity-gain bandwidth, 7.5ns
rise/fall time and 150V/ s slew rate. For single supply applications
such as video distribution or desktop multimedia, the CLC423
offers low 0.35%, 0.55° differential gain and phase errors.
The CLC423 provides high signal fidelity with -74/-94dBc 2nd/3rd
harmonics (1V
performance with CLC423’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 CLC423 is the perfect choice for composite
signal conditioning circuit functions such as active filters,
integrators, differentiators, simple gain blocks and buffering.
