LMH6882SQE/NOPB (TEXAS INSTRUMENTS)

The LMH6882SQE/NOPB is a high-speed high-performance programmable Differential Amplifier for use with zero IF sampling. The LMH6882 programmable differential amplifier combines the best of both fully differential amplifier and variable-gain amplifier. The device offers superior noise and distortion performance over the entire gain range without external resistors, enabling the use of just one device and one design for multiple applications requiring different gain settings. The LMH6882 is an easy-to-use amplifier that can replace both fully differential, fixed-gain amplifiers as well as variable-gain amplifier. The LMH6882 requires no external gain-setting components and supports gain settings from 6 to 26dB with small, accurate 0.25dB gain steps. As shown in the adjacent voltage gain chart the gain steps are very accurate over the entire gain range. With an input impedance of 100R, the LMH6882 is easy to drive from a variety of sources such as mixers or filters.
