The AD5424/AD5433/AD54451 are CMOS 8-, 10-, and 12-bit current output digital-to-analog converters (DACs), respect-ively. These devices operate from a 2.5 V to 5.5 V power supply, making them suitable for battery-powered applications and many other applications. These DACs utilize data readback, allowing the user to read the contents of the DAC register via the DB pins. On power-up, the internal register and latches are filled with 0s and the DAC outputs are at zero scale.
