illustrate
The DAC121S101 is a full-featured, general-purpose 12-bit voltage-output digital-to-analog converter (DAC) that can operate from a single +2.7 V to 5.5 V supply and consume only 3.6 volts at only 177 μA. THE ON-CHIP OUTPUT AMPLIFIER ALLOWS RAIL-TO-RAIL OUTPUT SWINGS AND 3-WIRE SERIAL INTERFACE CLOCKING FREQUENCIES UP TO 30 MEGAHERTZ OVER SPECIFIED SUPPLY VOLTAGE RANGES AND IS COMPATIBLE WITH STANDARD SPI, QSPI, MICROWIRE, AND DSP INTERFACES. Competing devices clock rates up to 20 MHz, supply voltages are limited in the 2.7V to 3.6V range.
Use the supply voltage of the DAC121S101 as a reference voltage to provide as much output dynamic range as possible. 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 function reduces power consumption by less than one microwatt.
The low power consumption and small DAC121S101 package make it an excellent choice for battery-powered devices.
The DAC121S101 is the AD5320 drop-in replacement and the DAC7512 is a family of pin-compatible DACs that include the 8-bit DAC081S101 and the 10-bit DAC101S101. The DAC121S101 operates over an extended industrial temperature range of -40°C to +105°C, while the DAC121S101Q exceeds the automotive grade 1 temperature range of -40°C to +125°C. The DAC121S101 is a 6-pin TSOT and 8-lead MSOP and the DAC121S101Q is only available on the 6-pin TSOT.
