... DGND GENERAL DESCRIPTION The AD5398 is a single 10-bit DAC with 120 mA output current sink capability. It features an internal reference and operates from a single 2 5.5 V supply. The DAC is controlled via a 2-wire (I operates at clock rates up to 400 kHz. The AD5398 incorporates a power-on reset circuit, which ensures that the DAC output powers and remains there until a valid write takes place ...

... To achieve the optimum θ recommended that the AD5398 is soldered 4-layer board. The AD5398 comes in an 8-lead LFCSP package with an exposed paddle that should be connected to the same potential as the AD5398 DGND pin per Jedec J-STD-020C. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection ...

... DAC register. Ideally, the output is 0 mA. The zero-code error is always positive in the AD5398 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. ...

... AGND receiving ACK, the master device can clock data into the AD5398 in a write operation can clock it out in a read operation. Data must change either during the low period of the clock, because SDA transitions during the high period define a start condition as described previously, or during a stop ...
