General Description


The DAC084S085 is a full-featured, general purpose QUAD 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7V to 5.5V supply and consumes 1.1 mW at 3V and 2.5 mW at 5V. The DAC084S085 is packaged in 10-lead LLP and MSOP packages. The 10-lead LLP 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 2.7V to 3.6V 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 1V and VA, 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 powerdown 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 is one of a family of pin compatible DACs, including the 10-bit DAC104S085 and the 12-bit DAC124S085. The DAC084S085 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.
