The AD5450/AD5451/AD5452/AD54531 are CMOS 8-/10-/12-/ 14-bit current output digital-to-analog converters （DACs）， respecttively. These devices operate from a 2.5 V to 5.5 V power supply， making them suited to several applications including batterypowered applications. As a result of manufacture on a CMOS submicron process， these DACs offer excellent 4-quadrant multiplication characteristics of up to 12 MHz. These DACs use a double-buffered， 3-wire serial interface that is compatible with SPI， QSPI?， MICROWIRE?， and most digital signal processor （DSP） interface standards. Upon power-up， the internal shift register and latches are filled with 0s， and the DAC output is at zero scale. The applied external reference input voltage （VREF） determines the full-scale output current. These devices can handle ±10 V inputs on the reference， despite operating from a single-supply power supply of 2.5 V to 5.5 V. An integrated feedback resistor （RFB） provides temperature tracking and full-scale voltage output when combined with an external current to voltage precision amplifier. The AD5450/AD5451/AD5452/AD5453 DACs are available in small 8-lead TSOT， and the AD5452/AD5453 are also available in MSOP packages. The AD5453 also comes in 8-lead LFCSP.
