General Description

The AFE5851 is an analog front-end targeting applications where the power and level of integration are critical.

The device contains 16 variable gain amplifiers (VGA), followed by an octal high speed (up to 65 MSPS) analog to digital converter (ADC).

Each of the 16 single ended inputs is buffered, accepts up to 1VPP maximum input swing and it is followed by a VGA with a gain range from –5dB to 31dB.
