MAXIM INTEGRATED / ANALOG DEVICES MAX9722AEUE Stereo Headphone Amplifier
The MAX9722AEUE+ is a 5V stereo headphone amplifier with differential inputs, direct-drive architecture, and shutdown capability, housed in a 16-pin TSSOP package. It features a ground-referenced output, eliminating the need for large DC-blocking capacitors, which reduces cost, board space, and component height. The gain can be adjusted externally. Designed to operate from noisy digital supplies, it offers an 80dB PSRR at 217Hz. The device includes two class AB headphone amplifiers, undervoltage lockout (UVLO), charge pump, and click/pop suppression circuitry. The charge pump inverts the positive supply to create a negative supply. It supports supply voltages from 2.4V to 5.5V and operates from -40°C to 85°C. Features include low quiescent current (5.5mA), short circuit and thermal overload protection, ±8kV ESD protection, and low harmonic distortion (0.009%). It can deliver up to 70mW per channel into 16Ω loads or 130mW into 32Ω loads. The device also supports low-power shutdown mode, reducing current to 0.1µA, making it suitable for portable audio applications.
