CLC411
High-Speed Video Op Amp with Disable
General Description
The CLC411 combines a state-of-the-art complementary bipolar process with National’s patented current-feedback architecture to provide a very high-speed op amp operating from ±15V supplies. Drawing only 11mA quiescent current, the CLC411 provides a 200MHz small signal bandwidth and a 2300V/µs slew rate while delivering a continuous 70mA current output with ±4.5V output swing. The CLC411’s high-speed performance includes a 15ns settling time to 0.1% (2V step) and a 2.3ns rise and fall time (6V step).
The CLC411 is designed to meet the requirements of professional broadcastvideosystemsincludingcompositevideoandhighdefinition television. The CLC411 exceeds the HDTV standard for gain flatness to 30MHz with it's ±0.05dB flat frequency response and exceeds composite video standards with its very low differential gain and phase errors of 0.02%, 0.03°. The CLC411 is the op amp of choice for all video systems requiring upward compatibility from NTSC and PAL to HDTV.
The CLC411 features a very fast disable/enable (10ns/55ns) allowing the multiplexing of high-speed signals onto an analog bus through the common output connections of multiple CLC411’s. Using the same signal source to drive disable/enable pins is easy since “break- before-make” is guaranteed.
The CLC411 is available in several versions:
