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 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 (100 kbps), fast (400 kbps), and fast+
(1.0 Mbps) modes.
The DACx0501 are available in easy-to-assemble
10-pin VSSOP and small 2-mm × 2-mm, 8-pin WSON
packages. The devices are fully specified over the
industrial temperature range of –40°C to +125°C.
