AD7225 CIRCUIT INFORMATION D/A SECTION The AD7225 contains four, identical, 8-bit voltage mode digital-to-analog converters. Each D/A converter has a separate reference input. The output voltages from the converters have the same polarity as the reference voltages, allowing single sup- ...

Only the data held in the DAC register determines the analog output of the converter. The LDAC signal is common to all four DACs and controls the transfer of information from the input registers to the DAC registers. Data is ...
