Texas Instruments' DAC80004/70004/60004 (DACx0004) are highly accurate, low-power, voltage-output, quad-channel, 16-, 14-, and 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 (maximum). 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 the status of the POR pin and remains in this state until a valid code is written to the device. These devices consume a 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 an 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.
