AFE5801 具有 ADC 的 8 通道 VGA
AFE5801 同类产品
- AFE5851 - 器件与被比较器件具有相同的功能，但并不是引脚对引脚等效，也有可能参数不相同。 Same functionality as AFE5801 with 16-channel and lower power
AFE5801 说明
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.
