The DAC128S085CIMTX/NOPB (购买请点击) is a full-featured, general purpose OCTAL12-bit voltage-output digital-to-analog converter (DAC) thatcan operate from a single +2.7V to +5.5V supply and consumes1.95 mW at 3V and 4.85 mW at 5V. The DAC128S085is packaged in a 16-lead LLP package and a 16-lead TSSOPpackage. The LLP package makes the DAC128S085 thesmallest OCTAL DAC in its class. The on-chip output amplifiersallow rail-to-rail output swing and the three wire serialinterface operates at clock rates up to 40 MHz over the entiresupply voltage range. Competitive devices are limited to 25MHz clock rates at supply voltages in the 2.7V to 3.6V range.
The serial interface is compatible with standard SPI™, QSPI,MICROWIRE and DSP interfaces. The DAC128S085CIMTX/NOPB (购买请点击) also offersdaisy chain operation where an unlimited number ofDAC128S085CIMTX/NOPB (购买请点击)s can be updated simultaneously using a singleserial interface.
There are two references for the DAC128S085CIMTX/NOPB (购买请点击). One referenceinput serves channels A through D while the otherreference serves channels E through H. Each reference canbe set independently between 0.5V and VA, providing thewidest possible output dynamic range. The DAC128S085 hasa 16-bit input shift register that controls the mode of operation,
the power-down condition, and the DAC channels" register/output value. All eight DAC outputs can be updatedsimultaneouslyor individually.
A power-on reset circuit ensures that the DAC outputs powerup to zero volts and remain there until there is a valid write tothe device. The power-down feature of the DAC128S085 allowseach DAC to be independently powered with three differenttermination options. With all the DAC channelspowered down, power consumption reduces to less than 0.3μW at 3V and less than 1 μW at 5V. The low power consumptionand small packages of the DAC128S085 make it anexcellent choice for use in battery operated equipment.
The DAC128S085CIMTX/NOPB (购买请点击) is one of a family of pin compatible DACs,including the 8-bit DAC128S085CIMTX/NOPB and the 10-bit DAC108S085.All three parts are offered with the same pinout, allowing systemdesigners to select a resolution appropriate for theirapplication without redesigning their printed circuit board. TheDAC128S085CIMTX/NOPB operates over the extended industrial temperaturerange of −40°C to +125°C.
