The D.Module.ADDA16 is based on the Analog Devices data converters AD7663 and AD5544. The analog front end digitizes up to 4 differential voltage inputs with 16-bit resolution and a sampling rate up to 250ksps. The four DAC outputs also deliver 16-bit resolution.
This is a legacy product, which is still in full production, however, not recommended for new designs. Please consider the D.Module2.ADDA500K16.
