These devices operate from a 2.5 V to 5.5 V power supply, making them suited to several applications including battery-powered 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 s...
