No description available.
This circuit shows a method which increases the power capability of a drive system for audio speakers. Two MAX4188 are used to operate on half cycles only, which greatly increases their power handling capability. Bridging the speaker, as shown, makes 200 mA of output current available to drive the load. The MAX4305 is used as an ac-coupled, low noise preamplifier, which drives the bridge circuit.
