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.

Product Detail

The evaluation board for the AD5449 contains an SDP connection and software which allows the AD5449 to be controlled from an SDP board.

The AD5449 can be used to evaluate the AD5425, AD5429 and AD5439 also.

The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
