The ADA4937-1 is a low noise, low distortion, high bandwidth, single supply differential ADC driver that can be used for ADC drivers, single-ended-to-differential converters, IF and baseband gain blocks, differential buffers and line drivers.
The ADA4937-1 is a low noise, ultra-low distortion, high speed differential amplifier designed to drive high performance ADCs with resolutions up to 16 bits from DC to 100 MHz. It features extremely low harmonic distortion, with 100 dBc SFDR at 10 MHz and 81 dBc SFDR at 70 MHz. The device supports both full differential and single-ended to differential gain configurations via an external feedback network.
