The BlackADC Board is FPGA based ADC board which can be configured to connect 16-Bit MCU, embedded system, or any digital system.
The board provides 8 channels AFE utilizing Analog Device AD7401 chip which can be configured up-to 20Mhz sampling frequency, accepting a differential input signal of ±250 mV (±320 mV full scale).
The AD7401A is offered in a 16-lead SOIC and has an operating temperature range of −40°C to +125°C.
Eight AD7401 chips are directly connected to Altera Cyclone IV FPGA, so that all the channels can be sampled and data capturing can be done simultaneously.
The data so captured is stored in internal FPGA RAM and be acquired by 16-bit expansion port.
Powered with 5V DC supply makes it very low power consumption board.
