The 16-bit DAC80502, 14-bit DAC70502, and 12-bit DAC60502 (DACx0502) digital-to-analog converters (DACs) are highly accurate, low-power devices with voltage output.

The DACx0502 offer linearity of < 1 LSB. The high accuracy combined with tiny package make 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 2.5-V, 5-ppm/°C internal reference, giving full-scale output voltage ranges of 1.25 V,
2.5 V, or 5 V. The DACx0502 incorporate 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 I2C mode using the SPI2C pin. In SPI mode, the DACx0502 use a versatile 3-wire serial interface that operates at clock rates up to 50 MHz. In I2C mode, the DACx0502 operate in standard (100 kbps), fast (400 kbps), and fast+ (1.0 Mbps) modes.
