Digital to Analog Converters - DAC IC 14-bit Serial IOUT
DAC 1-CH Segment 14-bit 8-Pin MSOP Tube
The AD5450/AD5451/AD5452/AD5453 are CMOS 8-/10-/ 12-/14-bit current output digital-to-analog converters, respectively. 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 utilize a double-buffered, 3-wire serial interface that is compatible with SPI®, QSPI™, MICROWIRE™, and most 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 parts 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 LFSCP. The EV-AD5443/46/53SDZ board is available for evaluating DAC performance. For more information, see the UG-327 evaluation board user guide.
