The DAC102S085 is a full-featured, universal dual 10-bit voltage output digital-to-analog converter (DAC) that can run from a single +2.7 V to 5.5V supply consuming 3V to 0.6 MW at 5V and 1.6 MW.
The DAC102S085 is available in a package, 10-pin LLP and MSOP package.
The 10-pin LLP package makes the DAC102S085 the smallest dual-channel DAC in its class.
The on-chip output amplifier allows rail-to-rail output swings and a three-wire serial interface to clock rates up to 40 MHz over the entire supply voltage range.
Competitive devices are limited to a clock rate of 25 MHz with a limited supply voltage ranging from 2.7V to 3.6V.
SERIAL INTERFACES COMPATIBLE WITH STANDARD SPI, QSPI, MICROWIRE AND DSP INTERFACES.
The DAC102S085 is referenced for two channels and can be used at 1V SUM

A variation that provides as much output dynamic range as possible.
The DAC102S085 has a 16-bit input shift register that controls the output, operating mode, power-down conditions, and binary input data to be updated.
Two outputs, which can be updated simultaneously or separately, depend on the setting of the operands for both modes.
The power-on reset circuit, which ensures that the DAC's output power is up to zero volts, still exists until there is a valid write device.
The power-down feature reduces power consumption less than microwatts with three different termination options.
The low power consumption and small package of the DAC102S085 make it an excellent choice for battery-powered devices.
The DAC102S085 is a pin-compatible DAC family that includes the 8-bit DAC084S085 and the 12-bit DAC122S085.
The DAC102S085 operates over the extended industrial temperature range of -40°C to +105°C.
