MAX9725AEBC+ [Analog Devices]

The MAX9725 series are fixed-gain (MAX9725A-D) or adjustable-gain (MAX9725E) stereo headphone amplifiers featuring Maxim's DirectDrive architecture. This architecture eliminates the need for large DC-blocking capacitors by generating a negative supply from a single 0.9V to 1.8V supply, resulting in ground-referenced outputs. The amplifiers deliver up to 20mW per channel into 32Ω with low 0.006% THD+N and high PSRR (80dB at 1kHz). They include integrated click-and-pop suppression, short-circuit protection, and ±8kV ESD protection on outputs. The devices consume low quiescent current (2.1mA for MAX9725A-D, 2.3mA for MAX9725E) and feature a low-power shutdown mode. Available in space-saving UCSP and QFN packages, they are ideal for portable audio applications.
