The AFE5801 is an analog front end, targeting applications where the power and level of integration are critical. The device contains eight variable-gain amplifiers (VGA), each followed by a high-speed (up to 65MSPS) ADC, for a total of eight ADCs per device.

Each of the eight differential inputs is buffered, accepts up to 2Vpp maximum input swing, and 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 antialias low-pass filter (with 3dB attenuation at 7.5, 10, or 14MHz) is also integrated between VGA and ADC, for every channel.

The VGA/antialias filter outputs are differential (limited to 2Vpp) and drive the onboard 12bit, 65MSPS ADC. The ADC also scales down its power consumption should a lower sampling rate be selected. The ADC outputs are serialized in LVDS streams, which further minimizes power and board area.

The AFE5801 is available in a 64-pin QFN package (9mm × 9mm) and is specified over the full industrial temperature range (–40°C to 85°C).
