Audio Amp Speaker 1-CH Mono 2.7W Class DG 12-Pin WLP T/R, MAX98308EWC+T, Maxim Integrated

The MAX98307/MAX98308 fully differential mono Class DG multilevel power amplifiers with integrated inverting charge pumps offer highly efficient, high-power audio solutions for portable applications. Class DG multilevel modulation extends the dynamic range of the output signal by employing a charge-pump-generated negative rail as needed to extend the supply voltage. This scheme results in high efficiency over a wide output power range. The ICs combine Maxim"s active emissions limiting edge rate and overshoot control circuitry with multilevel output modulation to greatly reduce EMI. These features eliminate the need for output filtering as compared to traditional Class D devices, reducing component count and cost. The MAX98307"s 16-pin TQFN package features an adjustable gain set by external resistors. The MAX98308"s space-saving 12-bump WLP package features an internally fixed gain of 8.5dB, 11.5dB, 14.5dB, 17.5dB, and 20.5dB set by a single gain input. Both devices operate over the extended -40°C to +85°C temperature range.
