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.
