Texas Instruments has announced two new fully differential amplifiers (FDAs) intended to improve performance in radar and test and measurement equipment and wireless base stations. The LMH3401 and LMH5401 FDAs provide DC-coupled applications with high-quality AC performance to improve system capabilities. They offer a higher bandwidth and slew rate, as well as lower distortion than existing ADC drivers.
The LMH3401 delivers 7 GHz of –3-dB bandwidth at 16-dB gain, a high slew rate of 18,000 V/µs, and low harmonic distortion of –77 dBc at 500 MHz. The LMH5401 can be configured for 6 dB of gain or more, delivering 6.2 GHz of -3 dB bandwidth at 12-dB gain.
The LMH3401 and LMH5401 are available in a 14-pin, 2.5-mm × 2.5-mm QFN package. The LMH3401 costs $8.95 and the LMH5401 coss $7.95 in 1,000-unit quantities.
