7-GHz ADC drivers bring AC performance to DC-coupled applications
The LMH3401 provides 16 dB of gain with higher performance than similar FDAs, while providing a 30% reduction in both size and power consumption. It delivers 7 GHz of -3-dB bandwidth at 16-dB gain, a slew rate of 18,000 V/µs, and 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. It has a slew rate of 17,500 V/µsec, harmonic distortion of -90 dBc at 200 MHz, and IMD3 of -90 dBc at 200 MHz.
Both the LMH3401 and LMH5401 deliver highest bandwidth and slew rate at low power; they also eliminate the need for baluns, converting a signal from single-ended to differential.
The LMH3401 and LMH5401 minimise data converter distortion from true DC to more than 1 GHz in receive and transmit applications. This enables system designers to optimise the performance of the company’s highest-speed data converters, such as the 12-bit, 4-GSPS ADC12J4000; 16-bit, 370-MSPS ADC16DX370; and 16-bit, 2.5-GSPS DAC38J84.
Evaluation modules are available for both the LMH3401 and LMH5401 at a price of $149. TINA-TI SPICE models and reference designs are also available to simulate system performance.
