Dual 12-bit DAC with buffered voltage output
The AD5322ARMZ is a dual 12-bit digital-to-analog converter from Analog Devices, delivering a buffered voltage output through a String DAC architecture. It settles to within 1 LSB in 10 µs, making it suitable for control-loop update rates in industrial automation or instrumentation where the output must track a setpoint within one sample period.
Linearity and temperature grade
This matters for precision trim applications where the output must never step backward as the code increases. The external reference input allows the full-scale output to be set by an external voltage, decoupling the DAC span from the supply tolerance. The reference input range tracks the analog supply, so a 2.5 V reference with a 5 V supply gives a 0–5 V output swing.
