3 Description
The DAC80004/70004/60004 (DACx0004) are highly
accurate, low-power, voltage-output, quad-channel,
16-, 14-, 12-bit digital-to-analog converters (DACs)
respectively. The DACx0004 devices are ensured
monotonic by design and offer excellent linearity of
less than 1 LSB (Max). The reference input of the
DAC is buffered internally using a dedicated
reference buffer.
The DACx0004 devices incorporate a power-on-reset
circuit that ensures the DAC output powers up at zero
scale or mid scale depending on status of the POR
pin and remains in this state until a valid code is
written to the device. These devices consume very
low current of 1 mA/channel making them ideal for
portable, battery-operated equipment. These devices
also contain a power-down feature that reduces
current consumption to typically 3 µA at 5 V.
The DACx0004 devices use a versatile 4- or 3-wire
serial interface that operates at clock rates up to 50
MHz. The DACx0004 devices also include a SDO pin
to daisy chain multiple devices. The interface is
compatible with standard SPI™, QSPI™, Microwire,
and digital signal processor (DSP) interfaces. The
DACx0004 devices are offered in easy-to-assemble
14-pin TSSOP packages or an ultra small 14-pin
VSON package and are fully specified over the
extended industrial temperature range of –40°C to
125°C.
