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).

AFE5801EVM — AFE5801 评估模块
AFE5801 评估模块 (EVM) 是一款用于开发 AFE5801 器件的平台。AFE5801 包含一个带数字控制功能的 8 通道压控放大器 (VCA) 和一个 8 通道 65MSPS 模数转换器 (ADC)。AFE5801 的模拟前端 (AFE) 电路将处理 8 个模拟输入信号；然后该器件中的 ADC 会将 AFE 的输出进行数字化处理。
请注意，评估 AFE5801EVM 时需要使用 TSW1400EVM（已停产）。我们建议您在获取 TSW1400EVM 后再购买 AFE5801EVM。
