DAC70004 - Ultra-Small, true 14-bit quad voltage output DAC with 1LSB INL/DNL

Updated : 2020-01-09 14:29:25
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 DACx0004devices are ensured monotonic by design and offer excellent linearity of less than 1 LSB (Max). Thereference 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 outputpowers up at zero scale or mid scale depending on status of the POR pin and remains in this stateuntil a valid code is written to the device. These devices consume very low current of1 mA/channel making them ideal for portable, battery-operated equipment. These devices alsocontain 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 clockrates 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 ultrasmall 14-pin VSON package and are fully specified over the extended industrial temperature range of–40°C to 125°C.
