DAC121S101是一个全功能的，通用的12位电压输出数字 - 模拟转换器（DAC），可以从单一的+2.7 V至5.5V电源供电，仅177μA的电流消耗在3.6伏特。
THE ON-CHIP OUTPUT AMPLIFIER ALLOWS A RAIL-TO-RAIL OUTPUT SWING THREE-WIRE SERIAL INTERFACE THAT OPERATES CLOCKED AT FREQUENCIES UP TO 30 MEGAHERTZ OVER SPECIFIED SUPPLY VOLTAGE RANGES AND IS COMPATIBLE WITH STANDARD SPI, QSPI, MICROWIRE, AND DSP INTERFACES.
Competing devices are limited to clock rates of 20 MHz and supply voltages are 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.
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.
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.
DAC121S101经营为-40 ° C扩展工业温度范围为105 ° C，而DAC121S101Q超过1级汽车级温度范围为-40 ° C至+125 ° C。
DAC121S101是在一个6引脚TSOT和8引脚MSOP和DAC121S101Q仅在6引脚TSOT。
