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 評(píng)估模塊

AFE5801 評(píng)估模塊 (EVM) 是一款用于開發(fā) AFE5801 器件的平臺(tái)。AFE5801 包含一個(gè)帶數(shù)字控制功能的 8 通道壓控放大器 (VCA) 和一個(gè) 8 通道 65MSPS 模數(shù)轉(zhuǎn)換器 (ADC)。AFE5801 的模擬前端 (AFE) 電路將處理 8 個(gè)模擬輸入信號(hào)；然后該器件中的 ADC 會(huì)將 AFE 的輸出進(jìn)行數(shù)字化處理。

請(qǐng)注意，評(píng)估 AFE5801EVM 時(shí)需要使用 TSW1400EVM（已停產(chǎn)）。我們建議您在獲取 TSW1400EVM 后再購買 AFE5801EVM。
