Explore the circuit

Select a stage to see its role and connections

Receive the code

The serial interface accepts the command and twelve-bit output setting.

Select the voltage

A resistive-string DAC uses VDD as its reference.

Buffer or power down

The output amplifier drives VOUT in Normal mode; power-down selects a resistor to ground.
