DACx0502 Dual Voltage-Output DACs
Texas Instruments DACx0502 Dual Voltage-Output Digital-to-Analog Converters (DACs) are highly accurate, low-power devices with voltage output. The DAC80502 is 16-bit, the DAC70502 is 14-bit, and the DAC60502 is 12-bit. The DACx0502 offers a linearity of < 1LSB. The high accuracy combined with tiny package makes the DACx0502 an excellent choice for applications such as gain and offset calibration, current or voltage set point generation, and power-supply control. These devices include a 2.5V, 5ppm/°C internal reference, giving full-scale output voltage ranges of 1.25V, 2.5V, or 5V. The Texas Instruments DACx0502 incorporates a power-on-reset circuit that makes sure the DAC output powers up at zero scale or midscale based on the status of RSTSEL pin, and remains at that scale until a valid code is written to the device. The digital interface of the DACx0502 can be configured to SPI or I 2 C mode using the SPI2C pin. In SPI mode, the DACx0502 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz. In I 2 C mode, the DACx0502 operates in standard (100kbps), fast (400kbps), and fast+ (1.0Mbps) modes.
