CLC430

CLC430 General Purpose 100MHz Op Amp with Disable June 1999 N CLC430 General Purpose 100MHz Op Amp with Disable General Description The CLC430 is a low-cost, wideband monolithic amplifier for general purpose applications. The CLC430 utilizes National’s patented current feedback circuit topology to provide an op amp with a slew rate of 2000V/µs, 100MHz unity-gain bandwidth and fast output disable function. Like all current feedback op amps, the CLC430 allows the frequency response to be optimized (or adjusted) by the selection of the feedback resistor. For demanding video applications, the 0.1dB bandwidth to 20MHz and differential gain/phase of 0.03%/0.05° make the CLC430 the preferred component for broadcast quality NTSC and PAL video systems. The large voltage swing (28Vpp), continuous output current (85mA) and slew rate (2000V/µs) provide high-fidelity signal conditioning for applications such as CCDs, transmission lines and low impedance circuits. Even driving loads of 100Ω, the CLC430 provides very low 2nd and 3rd harmonic distortion at 1MHz (-76/-82dBc). Video distribution, multimedia and general purpose applications will benefit from the CLC430’s wide bandwidth and disable feature. Power is reduced and the output becomes a high impedance when disabled. The wide gain range of the CLC430 makes this general purpose op amp an improved solution for circuits such as active filters, differential-to-single-ended drivers, DAC transimpedance amplifiers and MOSFET drivers.
