CADEKA Microcircuits has introduced 10 new high-performance amplifiers. The Comlinear CLCx601 family of dual-, triple, and quad-channel high-performance amplifiers utilise current feedback technology to provide 550MHz unity gain bandwidth, ±0.1dB gain flatness to 120MHz, and 1,500V/μs slew rate. These specifications combined with their large signal bandwidth, 200MHz at Gain = 2V/V and 4Vpp output, can meet the requirements of high-definition television (HDTV), set-top-box, and other multimedia applications. Providing over 50mA of output current, these amplifiers are also suited for video distribution systems.Offering a lower power alternative to the CLCx601 family, the Comlinear CLC2600 (dual), CLC3600 (triple), and CLC4600 (quad) consume 3.3mA of supply current per channel. With 300MHz of unity gain bandwidth, 1,300V/µs slew rate, 0.03%/0.04° differential gain/phase, and ±0.1dB gain flatness to 55MHz at 4Vpp, these amplifiers can meet the requirements for standard definition video requirements. Active filter applications, driving data converters, and instrumentation applications can also benefit from their high slew rate and wide bandwidth flatness. For power sensitive applications, such as portable video and instrumentation, the CLCx603 family of amplifiers consume 1.1mA of supply current per channel. The single-channel CLC1603 and triple-channel CLC3603 consume 0.11mA per channel when disabled. The combination of 140MHz large signal bandwidth, 450V/µs slew rate, 100mA output drive, and low power consumption make these amplifiers suited for many general purpose high-speed applications. The Comlinear CLC2000 is a dual voltage feedback amplifier that offers ±200mA of output current at 9.4Vpp. The CLC2000 is capable of driving signals to within 1V of the power rails. When connected as a differential line driver, the dual amplifier drives signals up to 18.8Vpp into a 25Ω load, which supports the peak upstream power levels for upstream full-rate ADSL CPE applications. The low differential gain/phase (0.009%/0.06°), low noise (4.5nV/√Hz), low 2nd/3rd harmonic distortion (-83dBc/-83dBc at 8.4Vpp), and high output current make the CLC2000 suited for Customer Premise ADSL or driving video over long lengths (up to 1km) of twisted pair cable.
