The DAC088S085 is a full-featured, general-purpose, OCTAL, 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 1.95 mW at 3 V and 4.85 mW at 5 V. The DAC088S085 is packaged in a 16-pin WQFN package and a 16-pin TSSOP package. The WQFN package makes the DAC088S085 the smallest OCTAL DAC in its class. The on-chip output amplifiers allow 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 range of 2.7 V to 3.6 V. The serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces. The DAC088S085 also offers daisy chain operation where an unlimited number of devices can be updated simultaneously using a single serial interface.

There are two references for the DAC088S085. One reference input serves channels A through D, while the other reference serves channels E through H. Each reference can be set independently between 0.5 V and V_A, providing the widest possible output dynamic range. The DAC088S085 has a 16-bit input shift register that controls the mode of operation, the power-down condition, and the DAC channels’ register and output value. All eight DAC outputs can be updated simultaneously or individually.

A power-on reset circuit ensures that the DAC outputs power up to 0 V and remain there until there is a valid write to the device. The power-down feature of the DAC088S085 allows each DAC to be independently powered with three different termination options. With all the DAC channels powered down, power consumption reduces to less than 0.3 µW at 3 V and less than 1 µW at 5 V. The low power consumption and small packages of the DAC088S085 make it an excellent choice for use in battery-operated equipment.

The DAC088S085 is one of a family of pin-compatible DACs, including the 10-bit DAC108S085 and the 12-bit DAC128S085. All three parts are offered with the same pinout, allowing system designers to select a resolution appropriate for their application without redesigning their printed-circuit board. The DAC088S085 operates over the extended industrial temperature range of –40°C to 125°C.
