ADC drivers enable high performance

Operating on a single 3-V supply, the LTC6400-20/LTC6401-20, A/D converter drivers are fully differential amplifiers that include gain-setting resistors in 16-lead QFN packages. The LTC6400-20 provides a fixed gain of 20 dB with 93-dBc third-order intermodulation distortion (IMD3 ) performance and noise figure of 6.5 dB for a 140-MHz input frequency.

The LTC6400-20 also consumes 90 mA and offers an adjustable output common-mode voltage of 1 to 1.6 V. Consuming just 50 mA, half that of the LTC6400-20, the LTC6401-20 maintains the same low-noise performance and –90-dBc distortion performance for input frequencies up to 70 MHz.
