Product Detailed Description for AD5449
The AD5429/AD5439/AD5449 are CMOS, 8-, 10-, and 12-bit, dual-channel, current output digital-to-analog converters (DAC), respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suited to battery-powered and other applications.
As a result of being manufactured on a CMOS submicron process, these parts offer excellent 4-quadrant multiplication characteristics, with large signal multiplying bandwidths of 10 MHz.
The applied external reference input voltage (VREF) determines the full-scale output current. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external current-to-voltage precision amplifier.
These DACs use a double-buffered, 3-wire serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and most DSP interface standards. In addition, a serial data out (SDO) pin allows daisy-chaining when multiple packages are used. Data readback allows the user to read the contents of the DAC register via the SDO pin. On power-up, the internal shift register and latches are filled with 0s, and the DAC outputs are at zero scale.
The AD5429/AD5439/AD5449 DACs are available in 16-lead TSSOP packages. The EV-AD5415/49SDZ evaluation board is available for evaluating DAC performance. For more information, see the UG-297 evaluation board user guide.
