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. 1 True 16-Bit Performance: 1 LSB INL/DNL (Max) Ultra Low Glitch Energy: 1 nV-s Wide Power-Supply Range: 2.7 V to 5.5 V Output Buffer with Rail-to-Rail Operation Current Consumption: 1 mA/Channel 50-MHz, 4- or 3-Wire SPI Compatible Interface SDO Pin for Readback and Daisy Chain Power-On Reset to Zero or Mid Scale Temperature Range: –40°C to +125°C Multiple Packages: – Tiny 14-Pin VSON – 14-Pin TSSOP 2 Applications • • • • 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.
