3 Description
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 I2C 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 I2C mode, the DACx0501 operate in
standard mode (100Kbps), fast mode (400Kbps), and
fast mode plus (1.0Mbps).
