DAC80501 的說明
The 16-bit DAC80501, 14-bit DAC70501, and 12-bit DAC60501 (DACx0501) digital-to-analog converters (DACs) are highly accurate, low-power devices with voltage-output. The DACx0501 are specified monotonic by design, and offer linearity of < 1 LSB. 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 DACx0501 incorporate a power-on-reset (POR) circuit that makes sure the DAC output powers up at zero scale or midscale, and remains at that scale until a valid code is written to the device. These devices consume a low current of 1 mA, and include a power-down feature that reduces current consumption to typically 15 µA at 5 V.
The digital interface of the DACx0501 can be configured to SPI or I 2C mode using the SPI2C pin. In SPI mode, the DACx0501 use a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz. In I 2C mode, the DACx0501 operate in standard mode (100Kbps), fast mode (400Kbps), and fast mode plus (1.0Mbps).
