TI DAC084S085CIMM/NOPB

The DAC084S085 is a full-featured, general-purpose QUAD 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single 2.7 V to 5.5 V supply and consumes 1.1 mW at 3 V and 2.5 mW at 5 V. The DAC084S085 is packaged in 10-pin SON and VSSOP packages. The 10-pin SON package makes the DAC084S085 the smallest QUAD DAC in its class. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25-MHz clock rates at supply voltages in the 2.7-V to 3.6-V range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces. The reference for the DAC084S085 serves all four channels and can vary in voltage between 1 V and V_A, providing the widest possible output dynamic range. The DAC084S085 has a 16-bit input shift register that controls the outputs to be updated, the mode of operation, the power-down condition, and the binary input data. All four outputs can be updated simultaneously or individually depending on the setting of the two mode of operation bits. A power-on reset circuit ensures that the DAC output powers up to zero volts and remains there until there is a valid write to the device. A power-down feature reduces power consumption to less than a microWatt with three different termination options. The low-power consumption and small packages of the DAC084S085 make it an excellent choice for use in battery-operated equipment. The DAC084S085 operates over the extended industrial temperature range of -40°C to +105°C.
