BlackAdADC 850
The BlackAdADC/DAQ Board is FPGA based ADC board which can be configured to connect Raspberry pi or any MCUs.
The board provides 8 channels AFE utilizing Analog Device AD9273 chip which can be configured up-to 50MHz sampling frequency, accepting a differential input signal of ±500 mV (±733 mV full scale).
The AD9273 is offered in a 100-lead TQFP and has an operating temperature range of −40°C to +85°C. AD9273 chip is directly connected to Altera Cyclone III FPGA, so that all the channels can be sampled and data capturing can be done simultaneously.
The data so captured is expended 16-bit word and stored in internal FPGA DPRAM.
Thus the data can be read/wrote to file in Raspberry board via SPI.
Powered with 5V DC supply makes it very low power consumption board.
