¡¡¡¡The AD54251 is a CMOS£¬ 8-bit£¬ current output digital-to-analog converter £¨DAC£© that operates from a 2.5 V to 5.5 V power supply£¬ making it suitable for battery-powered applications and many other applications. This DAC utilizes a double buffered£¬ 3-wire serial interface that is compatible with SPI?£¬ QSPI?£¬ MICROWIRE?£¬ and most DSP interface standards. An LDAC pin is also provided£¬ which allows simultaneous updates in a multiDAC configuration. On power-up£¬ the internal shift register and latches are filled with 0s and the DAC outputs are 0 V. As a result of manufacturing on a CMOS submicron process£¬ this DAC offers 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 I to V precision amplifier. The AD5425 is available in a small£¬ 10-lead MSOP package.
