The AD5449YRUZ is a CMOS 2-channel 12-bit current output Digital-to-analog Converter (DAC) operates from a 2.5 to 5.5V power supply, making it suited to many applications. As a result of being manufactured on a CMOS submicron process, this part offers excellent 4-quadrant multiplication characteristics with large signal multiplying bandwidths of 10MHz. 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. This DAC uses a double-buffered, 3-wire serial interface that is compatible with SPI, QSPI?, MICROWIRE? and most DSP interface standards. Data read-back 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.
