National Semiconductor has augmented its line of energy-efficient high-speed differential amplifiers with the LMH6552, LMH6515, and LMH6555 members of the company's PowerWise(R) family of products. The LMH6552 is a current-feedback amplifier with 1.5-GHz bandwidth and 0.1-dB gain flatness to 450 MHz. Harmonic distortion is only -74 dBc at 70 MHz making it ideal for boosting signals to 14-b ADCs at 70 MHz. Model LMH6515 is a digitally controlled variable gain amplifier (DVGA) with maximum gain of 26 dB and 31-dB gain adjustment range over a 3-dB bandwidth of 600 MHz. It allows gain to be adjusted in 1-db steps and provides a noise figure of 8 dB and output third-order intercept point of +40 dBm. Model LMH6555 is a differential driver optimized for DC-coupled, 8-b data-acquisition applications through 750 MHz. It features 53-dB spurious-free dynamic range (SFDR) at 750 MHz converting single-ended signals into differential outputs with 0.5-dB gain flatness through 330 MHz.
