... Power Amplifiers +1 -1 Figure 1. Bridge-Tied Load Configuration Applications Information The MAX9716/MAX9717 are designed to drive a load differentially, a configuration referred to as bridge-tied load or BTL. The BTL configuration (Figure 1) offers advantages over the single-ended configuration, where one side of the load is connected to ground. Driving the load differentially doubles the output voltage compared to a single-ended amplifier under similar conditions ...
