Features • Guaranteed Monotonicity • Low Power Operation • Rail-to-Rail Voltage Output • Power-on Reset to 0V • Simultaneous Output Updating • Wide power supply range (+2.7V to +5.5V) • Industry's Smallest Package • Power Down Modes Description The DAC102S085 is a full-featured, general purpose DUAL 10-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes 0.6 mW at 3V and 1.6 mW at 5V. The DAC102S085 is packaged in 10-lead LLP and MSOP packages. The 10-lead LLP package makes the DAC102S085 the smallest DUAL 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 2.7V to 3.6V range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE and DSP interfaces. The reference for the DAC102S085 serves both channels and can vary in voltage between 1V and VA, providing the widest possible output dynamic range. The DAC102S085 has a 16-bit input shift register that controls the outputs to be updated, the mode of operation, the powerdown condition, and the binary input data. Both 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 DAC102S085 make it an excellent choice for use in battery operated equipment. The DAC102S085 is one of a family of pin compatible DACs, including the 8-bit DAC084S085 and the 12-bit DAC122S085. The DAC102S085 operates over the extended industrial temperature range of −40°C to +105°C.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
