MAXIM INTEGRATED / ANALOG DEVICES MAX97220EETET Headphone Amplifier
The MAX97220E is a high-fidelity differential input headphone amplifier and line driver, suitable for set-top boxes, LCD TVs, and home theater systems. It features a charge pump that creates a negative rail, eliminating large coupling capacitors and reducing system size and cost. The amplifier offers 125mW power into 32Ω loads at 5V, with low THD+N below 90dB, and maintains excellent SNR performance. The device operates from 2.5V to 5.5V, with click-and-pop suppression and a shutdown mode for low power consumption. Its differential inputs enhance noise immunity, and the integrated charge pump simplifies design without compromising audio fidelity.
