Comlinear CLC427
Dual Voltage Feedback Amplifier
for Single Supply Operation
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
by its 4.3V_pp output voltage from a single 5V supply.
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
with -74/-94dBc 2nd/3rd harmonics (1V_pp, 1MHz, R_L=150Ω).
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.
