... DAC register. Ideally, the output is 0 mA. The zero-code error is always positive in the AD5398A because the output of the DAC cannot go below 0 mA. This is due to a combination of the offset errors in the DAC and output amplifier. Zero-code error is expressed in mA. ...

... DATA FORMAT Data is written to the AD5398A high byte first, MSB first, and is shifted into the 16-bit input register. After all data is shifted in, data from the input register is transferred to the DAC register. Because the DAC requires only 10 bits of data, not all bits of the input register data are used ...
