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.
