Abstract
A system including a converter, a buffer, and an offset adjust circuit. The converter is configured to provide, based on a digital input signal, a first output current. The buffer is configured to provide, based on the first output current, a second output current to an output pin. The offset adjust circuit is in communication with the first output current and is configured to, based on the second current at the output pin, adjust the first output current to compensate for a current offset at the output pin.
