MAX9725BEBC+ [Analog Devices]

The MAX9725 series are stereo headphone amplifiers featuring DirectDrive architecture, operating from a single 0.9V to 1.8V supply. They eliminate the need for large DC-blocking capacitors, saving board space and cost. Fixed-gain versions (MAX9725A-D) offer gains of -2V/V, -1.5V/V, -1V/V, and -4V/V respectively, while MAX9725E allows adjustable gain down to -1V/V using external resistors. The amplifiers deliver up to 20mW per channel into 32Ω with low 0.006% THD+N, high PSRR (80dB at 1kHz), integrated click-and-pop suppression, low-power shutdown control, short-circuit protection, and ±8kV ESD protection on outputs. Available in space-saving 12-bump UCSP and 12-pin thin QFN packages.
