MAX98314 Mono 3.2W Class D Amplifier with Integrated Input Coupling Capacitors
General Description
The MAX98314 mono 3.2W Class D amplifier provides Class AB audio performance with Class D efficiency. This device 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 IC's low 0.95mA at 3.7V, 1.2mA at 5.0V quiescent current extends 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. The IC is available in a small 9-bump, 0.3mm pitch WLP (1.0mm x 1.0mm
