These devices can handle 10 V tively. These devices operate from a 2.5 V to 5.5 V power supply, inputs on the reference, despite operating from a single-supply making them suited to several applications including battery- power supply of 2.5 V to 5.5 V. An integrated feedback resistor powered applications. (R ) provides temperature tracking and full-scale voltage FB output when combined with an external current to voltage As a result of manufacture on a CMOS submicron process, these precision amplifier. DACs offer excellent 4-quadrant multiplication characteristics of up to 12 MHz. The AD5450/AD5451/AD5452/AD5453 DACs are available in small 8-lead TSOT, and the AD5452/AD5453 are also available These DACs use a double-buffered, 3-wire serial interface that in MSOP packages. The AD5453 also comes in 8-lead LFCSP. 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. 1 U.S. Patent Number 5,689,257. Rev.
