Maxim MAX98314 Mono 3.2W Class D Amplifier

Maxim Integrated MAX98314 Mono 3.2W
Class D Amplifier

Maxim Integrated MAX98314 is the industry's smallest Class D amplifier solution. This mono 3.2W Class D amplifier provides Class AB audio performance with Class D efficiency. It offers five selectable gain settings (0dB, 3dB, 6dB, 9dB, and 12dB) set by a single gain-select input (GAIN). Active emissions limiting (AEL) edge rate and overshoot control circuitry and a filterless spread-spectrum modulation (SSM) scheme greatly reduce EMI and eliminate the need for output filtering found in traditional Class D devices. The MAX98314 features low quiescent current of 0.95mA at 3.7V, 1.2mA at 5.0V, allowing it to extend battery life in portable applications. Highly linear, integrated input coupling capacitors (CIN) reduce solution size and provide excellent THD+N, PSRR, and CMRR performance at low frequencies vs. standard Class D amplifiers using external input capacitors.
