5 Description (continued)

The reference for the DAC082S085 serves both channels and can vary in voltage between 1 V and VA, providing the widest possible output dynamic range. The DAC082S085 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. 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 0 V 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 DAC082S085 make it an excellent choice for use in battery-operated equipment.

The DAC082S085 is one of a family of pin-compatible DACs, including the 10-bit DAC102S085 and the 12-bit DAC124S085. The DAC082S085 operates over the extended industrial temperature range of −40°C to 105°C.
