The DAC124S085CIMM/NOPB(购买请点击) is a full-featured, general purpose QUAD12-bit voltage-output digital-to-analog converter (DAC) thatcan operate from a single +2.7V to 5.5V supply and uses360 μA at 3V and 480 μA at 5V. The DAC124S085CIMM/NOPB ispackaged in a 10-lead MSOP package. The on-chip outputamplifier allows rail-to-rail output swing and the three wireserial interface operates at clock rates up to 40 MHz over theentire supply voltage range. Competitive devices are limitedto 25 MHz clock rates at supply voltages in the 2.7V to 3.6Vrange. The serial interface is compatible with standardSPI™, QSPI, MICROWIRE and DSP interfaces.
The reference for the DAC124S085CIMM/NOPB(购买请点击) serves all four channelsand can vary in voltage between 1V and VA, providing thewidest possible output dynamic range. The DAC124S085has a 16-bit input shift register that controls the outputs to beupdated, the mode of operation, the powerdown condition,and the binary input data. All four outputs can be updatedsimultaneously or individually depending on the setting ofthe two mode of operation bits.
A power-on reset circuit ensures that the DAC output powersup to zero volts and remains there until there is a valid writeto the device. A power-down feature reduces power consumptionto less than a microWatt with three different terminationoptionsDAC124S085CIMM/NOPB(购买请点击).
The low power consumption and small packages of the DAC124S085CIMM/NOPB(购买请点击) make it an excellent choice for use in battery
operated equipment.The DAC124S085CIMM/NOPB(购买请点击) is one of a family of pin compatible DACs,including the 8-bit DAC084S085 and the 10-bitDAC104S085. The DAC124S085CIMM/NOPB operates over the extendedindustrial temperature range of −40°C to +105°C.
