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. The VGA gain is digitally controlled and the gain curves versus time can be stored in memory, integrated within the device using the serial interface.

A selectable clamping and anti-alias low pass filter (with 3dB attenuation at 7.5, 10 or 14MHz) is also integrated between the VGA and ADC for every channel. The VGA/anti-alias filter outputs are differential (limited to 2 VPP) and drive the on-board 12-bit 65MSPS ADC that is shared between two VGAs to optimize the power dissipation.
