The DAC084S085 is a full-featured, universal quad, 8-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7 V to 5.5V supply, consuming 2.5 MW and 1.1 MW at 3V and 5V. The DAC084S085 is a package, 10-pin LLP and MSOP package. The 10-pin LLP package makes the DAC084S085 the smallest quad DAC in its class. The on-chip output amplifier allows rail-to-rail output swing and a three-wire serial interface clock frequency up to 40 MHz over the entire supply voltage range. Competitive devices have limited clock rates of 25 MHz with supply voltages ranging from 2.7 V to 3.6 V. SERIAL INTERFACES COMPATIBLE WITH STANDARD SPI, QSPI, MICROWIRE AND DSP INTERFACES.
The reference for the DAC084S085 provides all four channels and can change the voltage by 1VandV one, providing as much output dynamic range as possible. The DAC084S085 has a 16-bit input shift register that controls the output, operating mode, power-down condition, and binary input data to be updated. All four outputs, which can be updated simultaneously or individually, depend on the operating bit settings for both modes.
Power-on reset circuitry ensures that the DAC output power is up to zero volts and persists until there is a valid write device. The power-down feature reduces the power consumption ratio below the microwatt with three different terminal options.
The low power consumption and small package of the DAC084S085 make it an excellent choice for battery-powered devices.
The DAC084S085 is a pin-compatible DAC that includes the 10-bit DAC104S085 and 12-bit DAC124S085 families. The DAC084S085 operates over the extended industrial temperature range of -40°C to +105°C.
