Working Principles

AD7228ABNZ operates by accepting digital input data and converting it into corresponding analog voltages. The digital data is received through the DB0-DB7 pins, while control signals such as WR (Write), CS (Chip Select), and CLK (Clock) are used to synchronize the conversion process. The converted analog voltages are then available at the AOUT1-AOUT8 pins.
