General Description

The MAX9725 fixed-gain, stereo headphone amplifier is ideal for portable equipment where board space is at a premium.

The MAX9725 uses a unique, patented DirectDriveTM architecture to produce a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height.

Fixed gains of -2V/V (MAX9725A), 1.5V/V (MAX9725B), -1V/V (MAX9725C), and -4V/V (MAX9725D) further reduce external component count.
