An interference-tolerant transmitter is provided. In accordance with various example embodiments, a transmitter circuit includes a control circuit configured to maintain the sum of current as applied to a load from respective high-side and low-side current sources at a target level (e.g., range). In some applications, clamp circuits are used to clamp current to high and low sides of the load respectively in response to changes at the low-side and high-side of the load.
