Outputs the voltage selected by the 12-bit DAC code.
Connect a high-impedance meter or suitable analog load.
The ideal scale uses VDD / 4096. Loading, offset, gain error and output headroom affect real results.
Supply and analog-output reference.
Join controller ground and measurement return.
The supply also determines the output conversion scale.
Use a clean 3.3 V rail, with 100 nF and local bulk bypass to VSS.
Supply noise and supply error directly affect the analog output.
Bidirectional open-drain data connection.
Connect to controller SDA and a pull-up to VDD.
Clock connection for the I²C controller.
Connect to controller SCL and a pull-up to VDD.
Sets the least-significant address bit; two upper address bits are factory options.
Tie LOW for 0x60 on the selected A0 orderable, or HIGH for 0x61.
Do not confuse the external A0 pin with the A0 suffix in the ordering code.
