Description:The MAX98306 stereo 3.7W Class D amplifier provides Class AB audio performance with Class D efficiency.
This device offers five selectable gain settings (6dB,9dB, 12dB, 15dB, and 18dB) set by a single gain-select input (GAIN).
Active emissions limiting, edge-rate, and overshoot control circuitry combined with a filterless spread-spectrum modulation scheme (SSM) provide excellent EMI performance while eliminating the need for output filtering found in traditional Class D devices. These features reduce application component count.
The IC's 2.0mA quiescent current with a 3.7V supply extends battery life in portable applications. The IC is available in a 14-pin TDFN (3mm x 3mm x0.75mm) package specified over the extended -40NC to +85NC temperature range.
