AD5339ARMZ

AD5339ARMZ is a dual 12bit buffered voltage output DAC. It operates from a single 2.5V to 5.5V supply, consuming 250μA at 3V. On-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7V/μs. A 2-wire serial interface operates at clock rates up to 400KHz. This interface is SMBus compatible at VDD <lt/> 3.6V. Multiple devices can be placed on the same bus. The references for the two DACs are derived from one reference pin. The outputs of all DACs can be updated simultaneously using the software active-low LDAC function. It has power-on reset circuit to ensure that the DAC outputs power up to 0V and remain there until a valid write to the device takes place. A software clear function resets all input and DAC registers to 0V. A power-down feature reduces the current consumption of the devices to 200nA at 5V (80nA at 3V). Typical applications include battery-powered instruments, digital gain and offset adjustment, programmable attenuators and industrial process control.
