DirectDrive, Stereo Headphone Detailed Description The MAX9728A/MAX9728B stereo headphone ampli- fiers feature Maxim’s DirectDrive architecture, eliminat- ing the large output-coupling capacitors required by conventional single-supply headphone amplifiers. These devices consist of two 60mW Class AB head- phone amplifiers, undervoltage ...

DirectDrive, Stereo Headphone Amplifiers with Shutdown Since the MAX9728A/MAX9728B do not require output- coupling capacitors, this problem does not arise. Additionally, the MAX9728A/MAX9728B feature exten- sive click-and-pop suppression that eliminates any audible transient sources internal to the device. Typically, ...
